for Peter and the Shadow Thieves by Dave Barry, Ridley Pearson, and Greg Call
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.
