I Was a Teenage Alien (Paperback, Climbing Rose ed.)

Oas is sent from her home planet of Zorca-twenty-three to rescue her brother Ralb from the worst humanoid known in the solar system-a teenage girl. With her traveling companions, Rotsen, a plant with an attitude who watches too many Sopranos reruns, and Lehcarr, a Venus Fly Trap with the habit of eating her friends, they set out to find Ralb. Traveling through a black hole, Oas is transformed from her ananoid shape into a teenage humanoid, becoming what she fears most-a teenager. They land in Bedrocktown to find the teenagers aren't as bad as they feared-they're worse. Zen her handler has warned her to stay away from pizza and popcorn but she tries both, with horrible results. She needs to find her brother, figure out how humans kiss, save the town from an E. coli outbreak, and meet Johnny Depp, not necessarily in that order. Then all she has to do is find her way home, but are her ties to Earth too strong?
