Some people are born boring. Some live boring. Some even die boring. Fred managed to do all three, and when he woke up as a vampire, he did so as a boring one. Timid, socially awkward, and plagued by self-esteem issues, Fred has never been the adventurous sort. One fateful night - different from the night he died, which was more inconvenient than fateful - Fred reconnects with an old friend at his high school reunion. This rekindled relationship sets off a chain of events thrusting him right into the chaos that is the parahuman world, a world with chipper zombies, truck driver wereponies, maniacal necromancers, ancient dragons, and now one undead accountant trying his best to "survive." Because even after it's over, life can still be a downright bloody mess.
