There's no way my mother would have let me read "Zombie in Love" when I was four to eight years old! It tells the story of Mortimer, a zombie who very much wants to be in love.
At the Zombie Nite Cafe, ghouls, werewolves, and veiny eyeballs order meals such as "scrambled brains" and "malformed meat patties." Another book designed for four-to-eight year olds.
Also available on eBay.
