Warren is a seven-year-old boy. Dragon is a seven-hundred-year-old dragon. Not that most people believe that. Most people are sure that Dragon is a stuffed animal. People such as Warren's twin sister, Ellie, who challenges Warren to a contest at their new school: making 100 new friends. Warren isn't so good at making friends, but he doesn't like losing to Ellie, and Dragon will help him. But the first day of school doesn't exactly turn out the way he'd hoped, and even worse, Dragon disappears! By the time Warren gets home, he's not only not made any friends, he's lost his best friend. First day of school jitters are entertainingly explored in this laugh-out-loud chapter book.
