Sadie Lester has been dumped with relatives for the summer. Boredom seems inevitable in her small Minnesota town until she meets Allie-a spiky-haired off-road biker with incredible grace and speed. Training for the upcoming bike race, Allie leads Sadie and cute fellow cyclist Joe up and down Mount Kato - an exhilarating rush that pushes their limits. The fun ends abruptly when they stray off the trail and find a priest, badly beaten and near death. After calling for help, Allie mysteriously disappears from their lives. Just like the trash littering the beautiful river bluffs, there's something foul afoot. Creepy rednecks are prowling the woods, the same ones who ran Sadie and Allie off the road one night. It's not until the day of the big race that Sadie finally learns the startling truth about Allie, her connection to the priest, and what drove her into hiding.
