Franny Stone has always been a wanderer. By following the ocean's tides and the birds that soar above, she can forget the losses that have haunted her life. But when the wild she loves begins to disappear, Franny can no longer wander without a destination. She arrives in remote Greenland with one purpose: to find the world's last flock of Arctic terns and follow them on their final migration. She convinces Ennis Malone, captain of the Saghani, to take her onboard, winning over his eccentric crew with promises that the birds she is tracking will lead them to fish.

As the Saghani fights its way south, Franny's new shipmates begin to realize that she is full of dark secrets: night terrors, an unsent pile of letters, and an obsession with pursuing the terns at any cost. When the story of her past begins to unspool, Ennis and his crew must ask themselves what Franny is really running toward--and running from.

Propelled by a narrator as fierce and fragile as the terns she is following, Migrations is both an ode to our threatened world and a breathtaking page-turner about the lengths we will go for the people we love.
