The Alien Who Preferred Fish — Blaine C. Readler

Space aliens have invaded the earth! Unfortunately nobody is even aware, at least until Gabe, pet-sitter by day and jump-blues bandleader by night, finds himself face-to-face with a raccoon that talks like Louis Armstrong. Ronny (he named himself after Ronald Reagan, thinking that this would elicit fond memories) explains that he needs Gabe's help to thwart a full-scale invasion of evil Demon-zombies. Gabe, though, can't shake the feeling that something smells . . . fishy.
