This one took me a little longer to get into than the author's other books, but in the end I couldn't put it down. Lots of twists that I didn't see coming, and one big one that I did. The interweaving of a present mystery with a past mystery was very well done. Lots of trigger warnings and lots of violence and language, but if you're a Karin Slaughter fan, you know that's what's coming. If you're not already a fan, start with the Will Trent series (it's Slaughter's best work), or with Pieces of Her, neither of which are very like the TV shows they inspired. (The books are infinitely better!)
