After "rotten bad year" on the mainland, eleven-year-old Jett returns to Newfoundland to spend the summer with his sprightly Grandma Jo (whose hair is dyed cotton candy blue to match her house), bringing along a shameful secret involving the betrayal of a friend. As summer unfolds, Grandma Jo nurtures in Jett his sense of caring for others while giving him space to breathe. Jett finds himself examining memories of his past like bits of sea glass-arranging them in a way he can make sense of as he struggles to come to terms with past mistakes. A powerful and engaging narrative, composed of artfully wrought vignettes, Ebb & Flow washes over the reader, pulling them into the mystery of what happened to Jett on the mainland, and into his journey to redemption.
