Anybody here seen Frenchie?

Eleven-year-old Aurora Petrequin's best friend has never spoken a word to her. In fact, Frenchie Livernois doesn't talk. Aurora is bouncy, loud and impulsive. Making friends has never come easily. When Frenchie, who is autistic, silently chose Aurora as his person back in third grade, she chose him back. They make a good team, sharing their love of the natural world in coastal Maine. In the woods, Aurora and Frenchie encounter a piebald deer, a rare creature with a coat like a patchwork quilt. Whenever it appears, Aurora feels compelled to follow. At school, Aurora looks out for Frenchie, who has been her classmate until this year. One morning, Frenchie doesn't make it to his classroom. Aurora feels she's to blame. The entire town begins to search, and everyone wonders: how is it possible that nobody has seen Frenchie?
