I still read actual physical books. I know. I am old school ;) I recently read My Abandonment by Peter Rock.
The book is about a young girl who lives with her father in a cave in a nature preserve. Everything is perfect until they are found out and the father is arrested. They end up moving to a farm where the father's slowly apparent mental illness worsens. I won't spoil the rest.
This book was wonderful. The narrator is the young girl and because of her age she is very unreliable. We only see things from her point of view, which is not necessarily the whole picture. Her voice is so strong, though, that you can really picture everything that is happening. The story becomes harder and harder to put down. I strongly recommend it.
