Migrations

Franny Stone has spent her life on the move, following the tides and the birds rather than staying anywhere for long. Now the wild is disappearing, and she arrives in remote Greenland with a single aim: to find the last Arctic terns on Earth and follow them on what may be their final migration, from the Arctic to Antarctica.

She persuades Ennis Malone, captain of the fishing boat Saghani, to take her aboard, promising his crew that the birds will lead them to fish in emptied seas. As the boat pushes south, her shipmates begin to suspect she is not who she seems. Troubled by night terrors and keeping a pile of letters she never sends, Franny carries a past that comes to light as the voyage goes on: her childhood, her marriage to the ornithologist Niall Lynch, and the reason she cannot stop running.
