After Frannie's father dies, she discovers a puzzle in her Dad's workshop with her name on it. This is no ordinary puzzle and, as Frannie starts to put it together, strange things start to happen. She finds herself being drawn into the world of the puzzle (quite literally). Frannie becomes convinced that the puzzle will lead her back to her Dad.
As a fantasy story, this book works pretty well, but Ephron's decision to add a BFF and a boy interest seems a bit forced. They don't really add much to the story and it seemed overall as if Ephron was trying to do too much. Still, the characters are interesting and the book is a good read.
