Bethany's perfect life has crashed. Her parents, always loving on her to the point of completely spoiling her, have abandoned her with her Aunt. They disappear without an explanation, without even telling her when they will see her again. Everyone Bethany knows is suddenly holding secrets from her, and all she can discover is through what she hears when she eavesdrops.
Haddix is an extremely imaginative author. Her books are well-written, but even more than that, she never writes a boring novel. Her endings surprise! Double Identity in particular twists at the end. Great summertime (or, end of summertime, now) read.
