Mason Buttle is the biggest, sweatiest kid in his grade, and everyone knows he can barely read or write.  These learning challenges are further compounded by his grief. Fifteen months ago, Mason’s friend, Benny, fell off a ladder in the Buttle family orchard and died.  Police officer, Lieutenant Baird, has been badgering Mason with questions ever since, certain that the boy knows more about the incident that he has divulged. Both Mason and his new friend, the very small Calvin Chumsky are teased and tormented by other boys in their neighborhood so they create a hidden underground haven for themselves.  Even though he has the support of a loving grandmother and uncle as well as a social worker he feels safe with, Mason’s world is upended again when Calvin goes missing. Mason finds himself in trouble again, desperate to find out what has happened to Calvin. An award-winning title of friendship and compassion perfect for readers who love an underdog hero.
