When she talks her way into a job skippering a Viking longship for a Hollywood film, Cass Lynch thinks her big break has finally arrived - even though it means returning home to the Shetland Islands, a place she hasn't set foot on since she ran away as a teenager to pursue her dreams of sailing. When a dead woman turns up on the boat's deck, Cass, her past and her family come under suspicion from the disturbingly shrewd Detective Inspector Macrae.

Cass must call on all her local knowledge of Shetland, the wisdom gained from years of sailing, and her glamorous, French opera singer mother to clear herself and her family of suspicion - and to catch the killer before Cass becomes the next victim.
