Some places hold more than mystery. They hold purpose. Summer break was supposed to mean long days at the river-not sitting on the porch in a cast while things between her parents grow worse. But that's the summer stretching ahead of 13-year-old Freddie Williams. When a strange neighbor named Gilbert appears and begins leading Freddie and her friends Sadie and Jimbo toward a place called Lantern Hollow, the trio stumbles into a quiet mystery filled with small wonders and unexpected kindness. The deeper they follow its clues, the more Freddie begins to understand that Lantern Hollow may hold more than secrets-it may be preparing her for something much bigger than she ever imagined.
