In this riveting and adventure-packed follow-up to Peter and the Starcatchers, we discover Peter leaving the relative safety of Mollusk Island—along with his trusted companion Tinker Bell—for the cold, damp streets of London. On a difficult journey across the sea, he and Tink discover the dark and deadly, slithering part-man/part-creature Lord Ombra. It seems that the dreaded Ombra has a variety of mysterious powers including the ability to make shadows disappear.

In this prequel to the classic tale of Peter Pan, an orphan boy named Peter and his mysterious new friend Molly overcome bands of pirates and thieves in their quest to keep a fantastic secret safe and save the world from evil.

In this action-packed third installment in the Starcatchers series, Peter and Molly find themselves in the dangerous land of Rundoon, ruled by an evil king who enjoys watching his pet snake consume those who displease him. But that's just the beginning of problems facing our heroes, who once again find themselves pitted against the evil shadow-creature Lord Ombra in a struggle to save themselves, not to mention the planet

One summer morning while Aidan and Sarah are visiting their grandfather, they discover a secret compartment in his battered wooden desk. Inside is a yellowed envelope that contains a piece of very thin, almost translucent, white paper, on which, handwritten in black ink, are a series of seemingly random lines; among them are what appear to be fragments of letters, but not enough to make sense. At the bottom of the page is a verse about Peter Peter and a reference to a real hotel in London. As it happens, the family is about to embark on a trip to Europe, so the children decide that while in London, they will try to locate the hotel.

The year is 1901--it's been twenty-three years since Peter and the Lost Boys returned from Rundoon. Since then, nobody on the island has grown a day older, and the Lost Boys continue their friendship with the Mollusk tribe, and their rivalry with Captain Hook. Meanwhile in London, Molly has married George Darling and is raising three children: Wendy, Michael, and John. One night a visitor appears at her door; it's James, one of Peter's original Lost Boys.

Little Scallop, a princess of the Mollusk tribe, longs to have a real adventure. So late one night, she and her mermaid friends sneak off to dive for pearls. They run into a fierce storm and a strange ship sailed by men who would love to capture a mermaid.
