When is a summer vacation not really a summer vacation?

Sunny Lewin has been packed off to Florida to live with her grandfather for the summer. At first she thought Florida might be fun — it is the home of Disney World, after all. But the place where Gramps lives is no amusement park. It’s full of . . . old people. Really old people.Luckily, Sunny isn’t the only kid around. She meets Buzz, a boy who is completely obsessed with comic books, and soon they’re having adventures of their own: facing off against golfball-eating alligators, runaway cats, and mysteriously disappearing neighbors. But the question remains — why is Sunny down in Florida in the first place? The answer lies in a family secret that won’t be secret to Sunny much longer. . .
