Just finished Jennifer Bradbury's Shift. Best friends Chris and Win, set out on a cross country bike trip just after graduation, planning to go from their hometown in West Virginia to Washington state, then take the bus home in time to go their separate ways to college. Seven weeks into the trip, Win suddenly takes off while Chris is fixing a flat, and Chris can't find him. Since Win had been grating on his nerves and doing stupid things most of the trip, Chris just gives up and goes home, figuring Win would do the same. But weeks later, as Chris is starting college, no one has heard from Win, and the FBI and Win's father are dogging Chris with questions. The story is told in alternating chapters, switching from the events of the trip to present day as Chris is being hounded with questions and is trying to figure out happened himself. An enjoyable read, good for both middle and high school students. No objectionable content, so fine for middle schoolers. High school students who may be contemplating a post-graduation adventure, or who have a friend like Win (annoying as heck, but you gotta love 'em cause you've been best friends as far back as you can remember), can relate.
