The Dragon Stone — Dian Curtis Regan

For years, Miggy and her friends have searched for dragon stones, but they've never found any. The stones are well hidden in the hills and valleys of Rocky Creek. One day, Miggy gets lucky. While searching for a glimpse of the rare Spinosaurus that has moved into Rocky Creek, she discovers a magic dragon stone. The clan's wise grannies have preached that whoever finds a dragon stone must keep it a secret or its ability to grant wishes will disappear. Miggy finds ways to use the dragon stone to rescue herself and her friends. But the day finally comes when even a powerful dragon stone may not save the Clan from ruin . . . until Miggy comes up with a brave and imaginative solution!
