Beyond the Night by Joss Ware

Beyond the Night by Joss Ware (aka Colleen Gleason). Romance. Post apocalyptic zombie romance. No you didn't misread that. Dread (nickname) is knocked unconscious with his friends and wakes up 50 years later to a whole new world with a crazy new civilization. More than just California has fallen into the sea. Not only has the world changed but they've changed too. More than one person has special powers. It was surprisingly fun to read.
