"You see, Eugene, (OR), is special…" Apparently, in a similar way that Sunnydale was. I think this comic is emulating Buffy the Vampire Slayer.
There are zombies, (every issue), a mummy (every issue), ghosts (every issue), were-dogs and werewolves (dogs in every issue, wolves,- almost every issue), and more monsters each time! There's even a government organization, V.E.I.L., of dead presidents! Protecting our country, of course, and another organization of monster hunters, The Fossor Corporation, called Fossors or "gravediggers", to which, Gwen's new boyfriend, Horatio, belongs.
But how long will he be with Gwen? Especially once he finds out she's a Revenant/Zombie? (And HOW can't he tell?? "Love is blind" only goes so far…
Back to "Eugene is special".. The "walls" are thin, letting some of the gravity go and letting monsters of all kinds in.
This series is the beginning of the tv series, but it's only loosely, very loosely, based on this series. In some ways, the tv show is MUCH better.
