Ten year-old Ellie just entered Middle School. It’s not easy making friends when you’re shy so Ellie prefers observing birds on the way to school, on the school playground or reading about them from the library books. One day, the school librarian decides to trust her by lending her a rare ornithology book. But when she arrives to bring it back, Ellie discovers that the library doors are already closed.
She decides to return it in person to the librarian, who actually lives on an island full of birds in the middle of the Loire river off Saumur… it’s the start of an initiatory trip for Ellie!
