内容简介：
Toby Oliver, a sarcastic twelve-year-old boy, hates bridges, boxes, being the new kid, and moving. So when his family's latest move brings him to Ciferin, he sees it as just another link in an unending chain of frustrating relocations. But Ciferin is not an ordinary town. After all, most other towns have kids, seasons other than summer, teachers that answer questions, and people who talk to each other. Toby thinks he and his younger brother Kevin might have found some clues to the town's past when they stumble across a silver box in the creek behind their house. But what do the three keys go to? Where did the old pocket watch come from? And what should they do with the list of rules? The one thing Toby is certain of is that he will have no trouble following rule number one: Trust No One.
