Wow! This is the most exciting and gripping thriller I’ve read in ages. This is part of a series by the author S.F. Baumgartner. This tense thriller follows the kidnap of Grace who is kept underground in a maze of corridors. Can she be saved? Who did this? I couldn’t put this book down and I highly recommend it. I suggest reading the series of books before this: Living Secrets, Forgotten Secret, Tangled Secrets. Superb and highly enjoyable.

The fourth installment in the Mirror Estate Series, plunges readers into a world rife with suspense, complex characters, and unexpected twists. As an author known for crafting intricate plots that keep readers on the edge of their seats, Baumgartner once again delivers a gripping narrative filled with hidden truths and dark secrets.

Thanks to Netgalley for this arc. This is a prequel of a series and book 4. I never read it before but it intrigued me so I took it right away there are recaps of the other books which is helpful! This is really interesting and the characters are very well fleshed out. Very well written too. It’s in third person with multi pov. This for me is sometimes hard to focus on because of how it’s written, sometimes simple is better but the storytelling is really great in this. There is a lot of secrets in this throughout and criminal acts too. Very action packed and it keeps readers engaged but personally for me there was a little too much going on all at once.

Fast-paced, action packed, page turner! Hidden Secrets is the 4th book (plus a prequel) in this series by S. F. Baumgartner. So many plot lines and characters that will give you whiplash unless you have read the books in order. Thankfully the author gives a recap of each book at the beginning of Hidden Secrets (just in case you need a reminder). Definitely kept me alert to follow all the clues.

Releases Sep 24th. I received a complimentary copy of this book. Opinions expressed in this review are completely my own.

Abducted. Trapped. Hunted. Grace Benson must find a way out… or die trying. After her harrowing escape from a kill order, Grace thought she’d return to a normal life, only to be abducted from her! Decent read! This book was a bit different for me?! This book had suspense, intrigue, action, murder, mystery, a good who done it and a few twists and turns. The story was interesting but I would say it wasn’t one of my top favorites! But I would recommend reading this book! Thank you NetGalley and the publisher for sharing this book with me!

Hidden Secrets: A Thriller was indeed a thriller, and a great one at that. It kept me up way too late finishing it.
