A very well crafted and exceptionally well researched book. I hadn’t realised it was the second in a series but after doing some research I found that although there are some same characters the two books are completely stand alone. The characters are all developed and interesting and if you like to end a book feeling just a tad anxious then this is definitely for you.

I wasn't sure about this book at first. It had some parts that confused me. But gradually I grew to like the main character and her quiet ways. The book has some science to it but it's kept on a pretty basic level of understanding. I liked Katie interactions with her co-workers and her boyfriend Justin. I felt the investigating was softly done and that the killer was a mystery right up to the ending. That there was a killer was a mystery right up to the end. I ended up enjoying this book. #AnAirThatKills #NetGalley

Loved this book! I am a scientist yet learned a lot as well. I felt that at the student level this book would be awesome. The characters were well developed and the plot kept me guessing. All of the time Katie spent at the laboratory, I felt tension and suspense.

Unusual and different types of characters blend together well in the story. Yet, the reader knows something sinister is going on...

Katie/Caitlin is always "on pins and needles" afraid that she may break her cover. Working with Lyle Linstrom, is a plus as is Justin, Katie's friend from her time working in Antarctica.

Highly recommend - give this book a try!

Many Thanks to Lion Hudson Ltd. and NetGalley for the great read!

Katie goes undercover as a technician named Caitlin to ferret out possible scientific fraud at an isolated BL3 research facility. One of her new colleagues falls grievously ill shortly thereafter, and Caitlin is forced to hide her medical background from the others while at the same time making the diagnosis no one else suspected. Movie buffs will be reminded of the time Harrison Ford secretly saved a patient’s life while posing as an orderly in The Fugitive. Many complications ensue as the team realizes that someone on site wishes them harm. The book gives a flavor of life in the lab while maintaining a sense of suspense. The various twists and occasional threat of danger keep the action moving along. The protagonist is appealing, and there are plenty of suspects to keep the reader guessing. The ending is satisfying, if not a huge surprise..

Thanks to Netgalley and the publisher for a digital advance review copy.

Thanks to the publisher and NetGalley for providing me with the e-ARC. I think with the Coronavirus possibly becoming a global pandemic this book's premise is even more scary and realistic.

A very well written and researched book. this book is the second in a series but can be read as a standalone. The characters are well developed,interesting and believable. The story line of this book is creepily timely so if you find current world situations frightening you want want to save this one for a later date. But this book is extremely good and I do recommend it!!

I received this book from NetGalley and Lion Hudson LTD for an honest review.

4,5 stars
After spending 6 months on a scientific expedition in Antarctica, Katie came back home in Ely to find that her friends have moved on in there life while she felt that her career was stagnating. To remedy her restlessness she decides to work in one of her friend's lab as an undercover technician named Caitlin to investigate the work of one of the researchers, who seems to have always "perfect results".
"An air that kills" was an interesting dive into the world of virology and tropical medicine. I was enchanted by the atmosphere of cat 3 labs and insectaries.
The mystery in the story was well constructed and kept me guessing until the end. The details were thorough and accurate and the dynamics between the characters were strong and lively. It's definitely not your usual morose thriller. the story got a sweet undertone of new friendships and the promise of love.

There were some details that I couldn't wrap my head around like Katie's illness, was it really the shingles, or did she got malaria too when she got bitten? and what happened Antarctica for Katie to be called a whistle-blower?
Highly recommended to all thrillers, and medical thrillers fans.
