Eleven-year-old Sunny Turner doesn't let the fact that she has Down syndrome stop her from participating fully in life. Whether she is at school, swimming with friends or helping her family with chores, she always tries to do her best. When she and her family move to their summer fish camp on a remote Alaskan island, Sunny encounters a menacing stranger. Why is he living in the cabin of old Pete, who mysteriously died last year? Does it have something to do with the secret Pete asked her to keep? Sunny doesn't know, but she's determined to find out.
