YA book, which I'm increasingly starting to really enjoy. I think my daughter will like this book. It has history, science, adventure, suspense. Two kids are accidentally sent back in time due to an "Anti-gravity" machine mishap. They surive on their wits, and a lot of good luck. The title of the book is a bit of a misnamer, and I think it has been renamed. While Gideon is a main character - the book really centers on Kate & Peter. I have the next two in the serious on my Zune from audible.com and am looking forward to hearing what happens next.
