Book excerpt: Three-time Newbery Honor winner Zilpha Keatley Snyder combines a cast of quirky characters with an eerie old mansion to create a spellbinding tale of mystery and magic. Harleigh J. Weatherby IV feels misunderstood. At age twelve he is about as tall as a six-year-old, and no one lets him forget it. At school the bullies nicknamed him “Hardly.” Now he is homeschooled at the Weatherby mansion, where strict Aunt Adelaide is always on his case about something. Then Harleigh meets Allegra. When she literally flies over the walls of Weatherby and into Harleigh’s life, the two form an unlikely friendship. Allegra is fascinated by the enormous Weatherby mansion, and against Harleigh’s orders, sneaks inside. Together they discover that someone is trying to find—and steal—the long-lost Weatherby treasure. Will Harleigh and Allegra be able to foil the villain and save Weatherby House?
