Based on my previous experiences with Mary Kubica's books (I've read The Good Girl and Pretty Baby, which I found relatively satisfying as thrillers go), Don't You Cry was pretty much what I expected, which really isn't a bad thing. 
 Mary Kubica's style is generally easy to read, and engaging even when things take a while to build or feel like they're dragging on, which happens a bit in this book. The general premise is relatively simple, and you're given enough information to have a pretty good idea of where things are going. To me, this makes the twists and turns believable without being fully predictable, and overall I enjoyed the story and most of the characters. Once I actually got into it, it was a pretty quick read, and I'll continue to read books by this author.
