Not a bad book, but I didn't enjoy it as much as I seem to remember enjoying the first one. There were a few weird bits. For instance, Theo wonders about the fact that there's no ransom note in the abduction, but of course most kidnappings (not by parents) are not for ransom. Of course, this is a kids book and I get not stating that, but I feel like there should have been a look. 
 I can't say I enjoyed the way things unfolded; it seemed random and overdone. The writing also felt awkward, not up to Grisham's usual standard. The story itself was pretty good, and did keep me wanting more.

 Here's my biggest problem with the resolution. The parents are separated but not divorced, so custody is still shared. That means her father taking her would not be kidnapping. So the whole legal issues are overblown, imo. It would be one thing if they were divorced, or had a temporary custody agreement from a lawyer, but I didn't get the impression that they did.
