Hailey and Claire are spending their last summer together when they discover something at the bottom of the murky pool at the Capri Beach Club. There in the depths is a mysterious and beautiful creature with a sharp tongue and a broken heart: a mermaid named Aquamarine who has left her six sisters to search for love on land. Now, as this mythological yet very real being starts to fade in the burning August sun, a rescue is begun. On the edge of growing up, during a summer that is the hottest on record, Hailey and Claire are discovering that life can take an unpredictable course, friendship is forever, and magic can be found in the most unexpected places.

Oak Grove is a dry, dusty town haunted by the memories of a past flood. Everyone dreads water—everyone except two brothers, Trevor and Eli McGill. Nicknamed Trout and Eel for their darting quickness and the thin webbing between their fingers and toes, the boys dream of the farthest seas and of a mysterious past they only half remember. In helping them reach their hearts' desire, Martha Glimmer, the boys' fierce and loyal friend, is intent on running away from memories of her old life—before her mother died, before her father lost himself in grief, before her heart was broken. Little do Martha, Trout, and Eel know that running away will leave them on a journey back to their own true natures.
