Tennis shoes among the Nephites.

This is one of the coolest books ever written. It's about a boy named Jamie- but he goes by Jim, and anyone who tries to call him Jamie, (a name he feels is better suited to girls and French poodles) had better 'have had two years of karate, because I've had one.' He travels into the past- the long past. As in Book of Mormon times! He has to figure out how to get 2,600 years back to the future, but he's stuck with the class geek, Garth Plimpton, and his annoying little sister, Jenny. This is one heck of a book!!
