Soundings: Journeying North in the Company of Whales - the award-winning memoir

From Mexico to the Arctic ice, grey whale mothers swim with their calves. Following them, by bus, train and ferry, are Doreen and her toddler Max, in pursuit of a wild hope.

Doreen first visited Alaska as a young BBC journalist reporting on climate change among indigenous whaling communities. There, drawn deeply into an Iñupiaq family and an ill-fated love affair, she joined the bowhead whale hunt out on the sea ice.

Years later, now a single mother living in a hostel, Doreen embarks on this extraordinary journey: following the grey whale migration back to the Arctic, where greys and bowheads meet at the melting apex of our planet.
