Black tide
(Book)

"A Tom Doherty Associates book"

"It was just another day at the beach. Then the world ended. Mike and Beth were strangers before the night of the meteor shower. Chance made them neighbors, a bottle of champagne brought them together, and a shared need for human connection sparked something more. Following their drunken and desperate one-night stand, the two discover the astronomical event has left widespread destruction in its wake. But the cosmic lightshow was only part of something much bigger, and far more terrifying. When a lost car key leaves them stranded on an empty stretch of Oregon coast and inhuman screams echo from the dunes, when the rising tide reaches for their car and unspeakable horrors close in around them, these two self-destructive souls must fight to survive a nightmare of apocalyptic scale.
