"Hendricks and Pekkanen are at the top of their game...You won't see the final twist coming." —People Magazine

Caught in a web of attraction, deceit and jealousy, Jess quickly learns that some obsessions can be deadly.

Overall, I enjoyed this book - a quick ride but ultimately predictable for me. Maybe I've read too many thrillers...?

I do love an enchanting villainess but Dr. Shields' motives almost bore me when I realize what's unraveling. Surely she could devote her obvious genius manipulations and skills of perception to something other than an unfaithful husband? I did appreciate the added layer of "who REALLY is the bad guy here?" and was pleasantly shocked once or twice.

Conclusion: Decent writing, predictable but fun anyway.

Enjoyed the creepy mind-effing resulting in Jess's second-guessing everything. Easily distracted, and a non-rapid reader lends to ability to overlook, or lose sight of potentially significant - or telling - details. Thus, also easily able to second-guess, in turn enjoy the read!

This book was really hard to get into until about page 200 and kept me engaged the whole time. At first it was confusing that they were from two different perspectives and that the doctor talked in third person about herself. But in the end it wasn’t too bad.

Lots of suspense and twists and turns. Characters were well established and fully developed. I usually don't like it when the author switches between characters telling the story, but this was rather easy to follow the shift. My only complaint might be it was a bit too long to get to the point.

I just didn’t find this suspenseful or very interesting and am tired of female psychiatrists and therapists being described in movies and books as these strange twisted creatures while male therapists are calm and smart. I’m not sure what the point was of this novel, well written and structured tho it was.
