Tsunami blue

"With her badass rain boots, her faithful dog, and the ability to predict the monster tsunamis that have reduced the US to a series of islands, Kathryn 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's 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."--Cover.
