After having his former nickname, 'Grim', stolen by a classmate, Andrew Radigan is riled right up. Now called 'Rusty', he and his classmates are sent off to Camp Killerdrop, famous for its giant, deadly chasm. As revenge for winning a fight against the Sheriff's son, Rusty is sent to clean the trash out of the chasm's lowest depths. There, he discovers an artifact, and when he returns, he's framed for theft! Now wanted dead or alive, he's running through the desert from the Sheriff and his former friend Flint, a skilled hunter and tracker.  If he can't find the rest of the Crow's Beak scythe before the week is up, they'll be paying to see HIS bones in the great divide.
