When Sea Becomes Sky by Gillian McDunn

Bex and Davey’s summer in the saltmarsh is different this year, thanks to the record-breaking drought. Even the fish seem listless—and each day the water level lowers farther. When they discover a mysterious underwater statue, they’re thrilled at the chance to solve the puzzle of its origin. But when they learn of a development plan that will destroy their beloved marsh, they need to act quickly. Unfortunately, sometimes progress happens whether you’re ready or not. What will it mean if Bex and Davey lose their corner of the marsh where otters frolic and dragonflies buzz—their favorite place to be siblings together?
Award-winning author Gillian McDunn crafts a gorgeous story of love and siblinghood, of secret statues and island life, of holding on and letting go.
