ritten novel" (Booklist, starred review) tells a gripping story about a boy from Scotland and a girl from West Africa who join together to save a migrating Osprey--and end up saving each other.

When Callum spots crazy Iona McNair on his family's sprawling property, she's catching a fish with her bare hands. She won't share the fish, but does share something else: a secret.
She's discovered a rare endangered bird, an Osprey, and it's clear to both her and Callum that if anyone finds out about the bird, it, and its species, is likely doomed. Poachers, egg thieves, and wild weather are just some of the threats, so Iona and Callum vow to keep track of the bird and check her migratory progress using the code a preservationist tagged on her ankle, no matter what.
But when one of them can no longer keep the promise, it's up to the other to do it for them both. No matter what. Set against the dramatic landscapes of Scotland and West Africa, this is a story of unlikely friendships, the wonders of the wild--and the everyday leaps of faith that set our souls to flight.
