Thunder on the Plains (PathFinders)

It's been two years and middle-school student Danny Wind is still not over his father's death. When his mom marries a white man and they move to a new "white bread" neighborhood, Danny's life changes. The school principal considers him a troublemaker and soon his mom decides to send him to a summer survival camp for Native American teens. Danny is sure he is in for a boring summer on the reservation — until he meets other Native kids, learns to ride and care for horses, develops a relationship with his grandfather, and soon finds himself rescuing bison in Yellowstone National Park.
