Washed up as a baby beside a remote lighthouse and raised by a mermaid, Alpha Lux was the first foundling at Haven Point. Now the lighthouse is a ramshackle home for any disabled person who needs somewhere to belong. Looting from passing ships to make a living, they call themselves the Wrecklings, and for the children of Haven Point life is spent adventuring on the wild shore (and getting into trouble with the grown-ups). But when Alpha spots a strange light up on the headland, she realizes that her beloved family are in danger of being discovered by Outsiders. With their home under threat, the Wrecklings must decide what kind of future they want . . . and what they're willing to do to get it.
