Clickers

Phillipsport, Maine, is a quaint and peaceful seaside village. But when hundreds of creatures pour out of the ocean and attack, its residents must take up arms to drive the beasts back. They are the Clickers, giant, venomous, bloodthirsty crabs from the depths of the sea. The only warning to their rampage of dismemberment and death is the terrible clicking of their claws. But these monsters aren't merely here to ravage and pillage. They are being driven onto land by fear. 

The first wave was just the beginning. The United States is in ruins. It has just suffered one of the worst hurricanes in history; the people are demoralized, and the president is a religious fanatic. Then things get really bad - the Clickers return. Thousands of the monsters swarm across the entire nation and march inland, slaughtering anyone and anything they come across. But this time, the Clickers aren't blindly rushing onto land - they are being led by an intelligence older than civilization itself. 

They thought it was over, but the second wave was only the beginning. In the aftermath of the Clickers and Dark Ones' siege, and a coup against an insane President, America rebuilds. Change has come, and a better future is promised to all. But promises can be broken, and there may be no future at all. Because deep beneath the ocean, a new terror awaits. Dagon, god of the Dark Ones, is waking up....And if humanity doesn't stop him, then mankind will face extinction.
