Princess Decomposia and Count Spatula by Andi Watson (graphic novel)
Princess Decomposia of the Undead is overwhelmed with work. Ghost papers to sign, alien reports to read, werewolf dignitaries to entertain...and her father the King is no help at all. But when a vampire with a sweet tooth joins the Royal Staff, some changes are on the wing...and so is a bit of romance.
A cute love story with plenty of unexpected twists. I've never considered Chocolate Monster Cake as a possible defense strategy for zombies...but maybe I should.
Recommended for ages 10 to adult. No cussing or sex, but lots of fun (un-) dead stuff.
