Calvin is in St. Augustine, Florida, house-sitting for his friend. While walking the dog, he notices a little girl watching him. Later that night, she's outside his window, pointing to the St. Augustine Lighthouse a few blocks away. Unsure who the girl is or if she's lost, Calvin investigates the historic site. Is the little girl trying to tell him something? Or is the lighthouse itself just a bygone beacon? Designed for Striving Readers. Features include author/illustrator biography and table of contents.
