Gil’s All Fright Diner is a comedic horror young adult novel by A. Lee Martinez.
Gil’s All Fright Diner has some great characters, starting with Duke and Earl, a werewolf and a vampire respectively. They’re just passing through when they get hired by Loretta to protect her diner. Then Earl meets a ghost in the cemetery across the street and they start up a romance. Then there’s Tammy, the jailbait sorceress and Chad her dupe boyfriend/acolyte.
Loretta has a problem—zombies keep attacking her diner. There’s a bigger problem she’s unaware of though, namely that Gil, the previous owner, built the place to call down the apocalypse. Gil is also semi-possessing Tammy, hence the zombie summoning, and both are semi-possessed by eldritch abominations.
Gil’s All Fright Diner is a blast. The ending is both surprising and satisfying. Definitely recommended.
