Battleship — Peter David

YOU SANK THE WRONG BATTLESHIP

During a routine naval drill at Pearl Harbor, American forces detect a ship of unknown origins that's crashed in the Pacific Ocean. Lieutenant Alex Hopper, an officer aboard the USS John Paul Jones, is ordered to investigate the ominous-looking vessel -- which turns out to be part of an armada of ships that are stronger and faster than any on Earth. And that's when the Navy's radar goes down. Ambushed by a ravenous enemy they cannot see, a small U.S. fleet makes their last stand on the open ocean, armed with little more than their instincts, to defend their lives -- and the world as we know it.
