In this riveting and adventure-packed follow-up to the award-winning New York Times bestseller Peter and the Starcatchers, Peter leaves the relative safety of Mollusk Island - along with his trusted companion, Tinker Bell - for the dark and dangerous streets of London. On a difficult journey across the sea, he and Tink discover the mysterious and deadly Lord Ombra, who is intent on recovering the missing starstuff - celestial dust that contains unimagined powers. In London, Peter attempts to track down the indomitable Molly, hoping that together they can combat Ombra's determined forces. But London is not Mollusk Island; Peter is not the boy he used to be; and Lord Ombra - the Shadow Master - is unlike anything Peter, or the world, has ever seen. Dave Barry and Ridley Pearson have done it again - written a compulsively readable, magical, impossible-to-put-down tale that will delight readers of all ages.
