A woman with a rare genetic illness must uncover her connection to a terrorist group before their next attack in this exciting new bio-thriller from the author of Disease X.

Lucas Grafton has spent the last ten years hunting the Conclave, a secret organization who took everything from him, including his very identity. Now he has a lead—an imminent terrorist attack on London—code-named “Descartes”. But he can’t connect the dots until a seemingly innocent woman appears during his stakeout.

Jenna Young can’t believe she was attacked and barely escaped with her life. Now she’s on the run with a stranger…and racing against the clock. With only a note left by her father after his death, telling her to use the code-word “Descartes” to get the pills that slow the progression of her illness, Jenna has only days before her body will start to rapidly deteriorate.

Lucas and Jenna must piece together why she’s wanted by a terrorist group she’s never heard of. And why, despite her claims that she needs an unknown and presumably illegal drug to stay alive, she seems to be getting stronger by the day…

This action packed thriller starts out on the Ivory Coast of Africa in a little village that has been razed to the ground with no survivors.

I am exhausted. I loved the book and I loved the cliff hangers.
This is a great read and an intriguing idea.
My heart felt for both the hero and heroine throughout the book.

Awesome book! Have stayed up way too late to finish it as I really could not put it down. Fast paced. Suspenseful. Thriller sci fi. I didn’t see the twists coming, although hindsight is 20/20 and perhaps I should have.

Thanks to NetGalley and the publisher for the ARC. Loved it and would thoroughly ...more

Cliffhanger and I am done

I was with the story through the torture, through the secret society,, though her changing, but I won't be reading the next book. The idea introduced at the end (and, yes, vaguely hinted at earlier,) turned me right off. Won't give it away for others. The writing is good, th ...more
