Welcome to the near future, where our blue planet has been forever changed by a series of deadly tsunami waves...
With her badass rain boots, her faithful dog, and the ability to predict the monster tsunamis that have reduced the Earth to a series of islands, Kathryn "Blue" O'Malley isn't afraid of much. Cut off from all society, she takes to the airwaves as Tsunami Blue, hoping to save something of humanity as the world around her crumbles. But Blue should be afraid, because her message reaches the wrong ears. . .
Now she is the target of ruthless pirates known as Runners who want to use her special talents for their own profiteering - as soon as they can find her. Blue's only shot at survival lies with the stranger who washes up nearly naked on her rocky beach. A man who might just be working for Runners himself. Torn between suspicion and attraction, the two will have to navigate a surging tide of danger if they hope to stay alive.
