Boog and her best friends, Cedrick, Jules, and Aaron--aka the Squad--stick together, no matter what. Now that vampires are back, they'll need to take their Vanquisher lessons more seriously than ever. But who is behind this return of the undead?

When strange disappearances keep happening across their community and the Department of Vampire Affairs not-so-subtly warns Boog's mom to keep quiet about vampires returning, it looks like uncovering the truth won't be so easy. The Squad is eager to kick some undead butt, but will they be able to convince their parents they are ready to fight alongside the Vanquishers?
