Fiery and fierce, computer geek and eco-activist, Abi is holidaying with her grandmother on an island off the Norwegian coast. Having developed and befriended an AI device, Moonlight, she hopes to organise a global protest. On the island, she learns her great-grandfather rejected the family’s whaling livelihood, instead creating the first whale song recording. Inspired by him, Abi and Moonlight translate the whales’ songs and discover their stories. Whales are under threat, their numbers rapidly dwindling. Abi is determined to help.
