The premise is fairly solid--the daughter of a convicted serial killer is now an FBI profiler who is being played with by a serial killer who is out to get her in the end. This, in a nutshell, is what the book is about. The characters are in between solidly outlined and cookie-cutter ones, but I am just so sick and doggone tired of love triangles, and while there isn't quite one, there is a quasi one, and, to be frank, it wasn't quite believable.
What I did like was the idea that her mental health isn't where it needs to be yet, but to say more is a spoiler. While I am a Christian, I had a difficult time buying how the characters became Christians--again, a bit too cookie-cutter, but I disagree with the atheist reviewer who thought it was dissing all other forms of faith--those weren't even mentioned, but by and large if you read Christian fiction you can rest assured it is written for a Christian audience and they are rarely deep or philosophical which is why I read so few of them.
So, I'm hovering somewhere around 2.5 stars, and thought it might be a 3, but that wouldn't be honest. If I hadn't been reading this for a discussion, I'd have discarded it, and while the suspense did build, it wasn't enough to compensate for the writing which was solid but nothing special.
