How can a guy who can't find two matching socks be qualified to lead anyone?

An ancient prophecy declared that Zack Thomson, orphaned son of a great vampire hunter, would come back from the dead and either lead humanity into the light—or destroy it. Now the End of Days for vampires is here, the old order is eroding, and from the ashes of that ruin a new world will arise. Will Zack become the great leader the new order so desperately needs? And which of his friends, allies and enemies will survive to learn the answer?
