Gr 4-8-This fast-paced fantasy relates the adventures of 13-year-old Jessica Ross, who has been traveling around the world with her father and younger brother since her mother's death. In Ireland, she discovers that her nightmares of a haunting figure asking for help to find lost treasure are actually mysterious appearances by the Pirate Queen Grace O'Malley. Jess's gift of timewalking (moving back in time at the will of another) is revealed and she becomes enmeshed in a Timewalker Quest for the Pirate Queen. Bauer has created a contemporary world haunted by its past, with nearly nonstop action and a fairly well-developed mythology. Unfortunately, she has tackled too much for such a brief volume. The locales are often difficult to visualize and try too hard to be exotic, and the Timewalker history is too complex to be synopsized. The author relies too heavily on action and dialogue to carry the story, and not enough on character development.-Melissa Moore, Union University Library, Jackson, TN Copyright 2005 Reed Business Information.
