Peter and the Sword of Mercy (Starcatchers Series #4)

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.
