It's fishing season, and Kate Shugak is working with Old Sam aboard the fish tender Freya when Cal Meany floats up dead. His reputation as a womanizer, strike breaker and abusive father ensures that there are several suspects, multiple motives, and quite possibly more than one murderer. While Kate investigates the killing, her aunties mend nets, operate an illegal fish camp and impart cultural wisdom to Jack and his son Johnny. Ultimately, Kate finds herself in grave danger, as even her aunts join the list of suspects.
