Deep in the heart of Texas, Morganville is a small college town full of laid-back students and eccentric townies, not to mention the sort of creatures you wouldn't want to run into after dark. Despite their obvious differences, the human and vampire residents of Morganville have learned to coexist, but that doesn't stop genius student Claire Danvers from keeping up her guard. Because in Morganville, nothing is as it seems...

While developing a new system to maintain the town's defenses, Claire discovers a way to use the vampires' powers to help keep outsiders from spreading news of Morganville's unique situation once they've crossed the city limits.

But the new system has an unexpected and possibly deadly consequence: People inside the town start forgetting who and what they are - even the vampires. And when Claire's boyfriend, Shane, and her best friend, Eve, start treating her like a perfect stranger, Claire realizes she has to figure out a way to pull the plug on her experiment - before she forgets how to save herself... and Morganville.
