Surprises abound during the Weber family's first summer running an inn in rural Massachusetts. Before she agrees to go, Lucy Weber, 15, extracts from her parents a promise that she can return to N.Y.C. for school. Brother Henry (13) and Nathan (9) are more eager to take part. However, Nathan begins to see a ghost soon after their arrival, while Henry starts to consider dropping out of school to work on a fishing boat. Meanwhile, their parents cope with staff problems, the unexpected arrival of feckless cousin Joan, difficulties with guests, and--in a climactic episode--a hurricane that tests everyone's mettle, even the ghost's. Though much of the story here is told from Lucy's point of view, the vantage point bounces from Weber to Weber; the writing and characterization are utilitarian, but the action does build and the denouement is both satisfying and believable. An entertaining page-turner by a veteran author of juveniles.
