I like reading books about war dogs, shipwrecks, and lady aviators.
...Yowza. This book is heavy and, despite what the blurb on the back says, pretty damn hopeless. It's the story of a girl kidnapped and held captive by a pedophile for five years. That should give you a pretty good idea of what to expect. It's graphic and hard to read. It's quite short, less than 200 sparse pages, but I had to put it down several times, just because it's so emotionally wracking.
I actually read this once before, years ago for an Young Adult lit class. I picked it up again after seeing someone talking about it online. I was surprised that I had completely misremembered the ending. In my mind, I had rewritten a much more hopeful outcome, and maybe because of that, I felt myself more deeply affected by the story this time around.
