Surrounded by Sharks — Michael Northrop

He couldn't sleep. That's how it all started.

When Davey wakes, just as the sun is rising, he can't wait to slip out of the crammed hotel room he's sharing with his family. Leave it to his parents and kid brother to waste an entire day of vacation sleeping in! Davey heads straight for the beach, book and glasses in hand, not bothering to leave a note. As the sparkling ocean entices him, he decides to test the water, never mind that "No Swimming" sign. But as the waves pull him farther from shore, Davey finds himself surrounded by water -- and something else, too. Something circling below the surface, watching, waiting. It's just a matter of time.
