When Leticia Fitzgerald is offered a once-in-a-lifetime “rebirth” by Newport Biodyne—one that promises a new childhood inside a wealthy family—she says yes. The procedure is stranger than it sounds: microscopic parasitic organisms that graft themselves to a host, allowing a chosen outsider to become their baby overnight. It seems like fortune at last. Leticia moves into the Brocks’ cliffside estate in Maine, learns to play the part of adored daughter, and finally tastes the security she’s always wanted. But the parasites—called crabborn—do more than swap identities. They change appetites, loyalties, and bodies. Leticia’s new “parents” develop a maddening craving for crab meat and a faint but growing rot beneath their skin. The house’s real daughter, Angela, is already suspicious. And Newport Biodyne’s manager, Ezekiel Castro, has far darker plans than a simple adoption scheme. As Leticia fights to keep her pretend life intact, she discovers the company’s market: manufacture dependency, harvest heirs, and sell a lifetime of servitude. Betrayals pile up, monsters multiply, and the line between victim and accomplice disappears. To survive, Leticia must decide whether to sever the parasite—and the fake family—or become the very thing that used her to climb. A fast, sharp paranormal thriller about identity, class, and what it costs to be reborn.
