JD Barker is a master of his art. I became a huge fan after 3rd Monkey and absolutely loved this novel.

The final act becomes a chaotic wave of events that I couldn’t stop reading.

I am not even sure what to say about this one. I could take this review in a couple different directions. Do I praise it for its dark and depravity twists and turns? Do I praise it for its dark undertones regarding putting too much of our lives into an app? Do I praise the cautionary tale of mixing tech and mental health services? They all can apply.

Maybe I just need to say how much I enjoyed this. I was hooked from the start. The idea of an app running your life isn't off base at all. We are all guilty of it to some degree (some more than others). This book is dark, twisty, devilish, a little sultry, and a lot mind blowing.

I highly suggest this one, especially if you are looking for a multi-layered book that will keep your brain on overdrive from start to finish.

Abby & Brendan are suggested by their therapist to download the Sugar & Spice app to improve their love life. Once they download all hell breaks loose and they soon lose control over every tiny bit of action in their life. They didn't realize that their life could be controlled via an app and every smart gadget they own!

An app that leads to mayhem, murder and running to save their lives - Abby & Brendan have to face all kinds of crazy "sugar" and "spice" instructions.

Overall a great idea, but somewhere the book lost it's plot and regained towards the end - but I thoroughly enjoyed this!

An excellent thriller with multiple twists and turns. The writing is engaging and the characters fascinating. I never knew where the story was going and was kept on the edge of my seat throughout!

I enjoyed this book a lot. It surprised me because it wasn’t at all what I was expecting. I put this book off for a long time because I thought it would be smutty. I’m not into that at all. I love a good domestic thriller though. Spoiler: I didn’t think it was very smutty but it did have a lot of action!

Abby and Brendan have been together for 12 years and they are struggling to reconnect both in and out of the bedroom. They go to a therapist and she recommends they try out an app called Sugar and Spice to help reconnect. The app is basically like truth or dare for adults. You get points for completing sugars which is basically a conversation started or spices which are steamy dares like having sex in the bathroom at a restaurant. I was worried that the book would be centralized around their sex life but it’s not at all. The book had my jaw dropping and turning the pages quick to see what would happen next. The book had me asking a lot of questions about what I would do. Soon this app is taking over their lives and causing a lot of issue. People are dropping like flies and I’m just wondering how it’s all connected.

I recommend this book to anyone that loved the 4MK series.

This suspense thriller serves as a cautionary tale. Be careful...

If ever there was a book that would make me think long and hard about all my connected electronics, this was it. Our smart homes, smart phones, and all of the social media combined with the extensive list of apps should give us pause. What do we really know about what all of that is tracking in our lives.

Abby and Brendan Hollander are going through a bit of a rough patch in their marriage. A therapist suggests they download the new popular app, Sugar & Spice, to bring some excitement and intimacy into their relationship. What could go wrong -- it's just an app. A little bit of fun, right? After all, no one can MAKE you do anything you don't want to do, correct? Little do they know...

No spoilers here but I almost DNF because of all the violence and graphic sex details. I didn't really like any of the characters who just made one bad decision after another. The premise and concept were unique, and I wanted to see how it played out, so I did finish. I tried listening to the audiobook while following along with the e-book ARC (provided by the publisher), but the narrator was so bad at doing women's voices that I had to stop. I've found it's always a mistake to have only a single narrator for most books and it definitely negatively affects the quality of the production.

I've loved other books by this author, but this was a disappointment.

Sugar or Spice what would you pick.. It’s was just suppose to be a game until it wasn’t. It’s amazing what you will do for the right motivation. We take a look at a married couple Abby and Brendan who aren’t so happy a the start of the book but as it progresses they grow closer together as the game takes a dangerous and unexpected turn. I did figure out part of the twist at the end but man it still took me for a loop. Do your self a favor and read this book and if you have not read anything f by JD Baker what are you waiting for

This book didn't quite resonate with me. I didn’t gel with the characters, they seemed too shallow. I hated Romeo and Juliet, they were very irritating.

Make sure to read the author's note on his inspiration for this novel. I think it’s something we’ve all experienced …😉
Original, dark, well written, thought provoking, and captivating.

J.D. Barker’s book “Behind A Closed Door” delves into Abby and Brendan Hollander's attempt to revive their marriage through a counselor recommended app called Sugar and Spice. Initially adding excitement, the app soon spirals into a series of increasingly dangerous and kinky tasks, consuming their lives and invading their privacy.

This book didn't quite resonate with me. If I had picked it up without knowing the author, I would have easily assumed it was written by a man.

2/5 stars

JD does it again! I couldn't put this book down at all, one of my 5 star reads of the year. It had so many twists and turns I was on the edge of my seat the whole time. Makes you think twice on an app you're gonna download. Thank you for this arc!

A thriller that is a web of suspense, seduction, and danger. There are unpredictable twists with a fast pace.
Many thanks to Hampton Creek Press and to NetGalley for providing me with a galley in exchange for my honest opinion.

Wow! I can’t believe this is my first J.D. Parker book, and it certainly will not be my last! What an incredible ride!

Behind a Closed Door is a great thriller, and I’m so excited to see how they do it justice in movie format.

“Would you kill a stranger to save your spouse?” A couple with marital issues download an app to help them out - Sugar & Spice. Like a truth or dare game for adults. What starts out as way to get them out of their comfort zone and expand in the marriage and in the bedroom, turns out to be deadly.

I really enjoyed this. It kept me captivated throughout, and couldn’t wait to see what was around each new corner.

Thank you to NetGalley for this ARC in return for my honest review.

"Behind a Closed Door" by JD Barker is a masterful blend of psychological thriller and classic mystery. Barker expertly crafts a tale filled with twists and turns, keeping readers on the edge of their seats from start to finish. The story delves deep into the human psyche, exploring themes of trust, deception, and the haunting remnants of past traumas. Each character is meticulously developed, their secrets unraveling in a gripping narrative that culminates in a truly unexpected climax. This novel is a must-read for fans of intense, character-driven thrillers that leave a lasting impact long after the final page is turned.

This was a really good book with a lot of twist and turns. The main couple Abby and Brendan are looking to repair their relationship. They are told to download an app called sugar and spice. This app is not all that it’s cracked up to be, while bringing them together is it also tearing them and others apart? I really enjoyed this book, but at times I thought certain parts dragged out a little.

Ich weiß ehrlich gesagt nicht, wie ich dieses Buch bewerten soll, da ich es aufgrund relativ kurzer Ausleihdauer (ohne Verlängerung) nicht lesen konnte.

Ever wondered what would happen if your relationship therapy came with a side of tech and a sprinkle of danger? Dive into the rollercoaster that is Abby and Brenda’s marriage in this thrilling read!

When Abby and Brenda find their marriage on the rocks, they turn to couples counseling for a lifeline. Enter their therapist’s unconventional solution: the Sugar and Spice app. Sounds cute, right? Well, it starts off that way. The app assigns them fun tasks to rekindle their spark and awards points for each completed task. But hold on to your seat, because things quickly take a wild turn. What begins as simple and sweet soon spirals into a series of dangerous dares, making it seem like the app has a sinister agenda of its own.

This book is a mixed bag of suspense and slow burns. The concept is fresh and intriguing, pulling you in with the promise of tech-driven therapy gone awry. There are moments of genuine tension and excitement as Abby and Brenda navigate the increasingly perilous challenges. You’ll find yourself rooting for them, cringing at the danger, and questioning what’s coming next.

However, be prepared for a bit of a bumpy ride. There are sections where the pacing lags, and the narrative gets bogged down with overexplained details. These parts might have your mind wandering, but hang in there—the plot picks up again and keeps you engaged till the end.

Despite these slow patches, it’s an enjoyable read overall. The author’s creativity shines through, and there’s enough suspense and emotion to keep you turning the pages. This is my second book from this author, and I’m definitely looking forward to seeing what other intriguing tales they have up their sleeve.

In a nutshell, if you’re in the mood for a story that mixes marital drama with a techy twist and a dash of danger, give this book a try. Just be ready for a few slow spots, and you’ll find yourself entertained by this unique and thrilling journey.

I’m not sure how I feel about this book. On one hand, there were parts I enjoyed, but on the other hand, everything seemed so far fetched and over the top.

Abby and Brendan are having trouble in their marriage, so they decide to download an app to help them get their spark back. Things start off well as they reconnect and explore their relationship by doing small dares. However, the app soon turns sinister as the dares get more and more dangerous.

If you’re able to suspend your disbelief and just want a wild ride, I’m sure you’ll love this. However, after loving the 4MK series so much, I was a bit disappointed. The premise seemed really interesting, but something about this book just didn't work for me.

I'm lucky I picked this book when I was sick or I'd have got no work done and it helped me keep my mind off how everything sucked 😂

This book was unbelievable. The synopsis was very interesting and the book delivered what it promised. In most books, the middle part is the most likely to drag. In this book, however, when I reached about 50%, I was gobsmacked at some of the twists. And then the twists just kept coming. Were they believable? Absolutely not. Was it fun? Oh hell yes.

The only reason I'm not giving this one five stars is because the twists were a little over the top, but you better believe I'm combing through J.D. Barker's backlist after this
