Rocket Roll — H.C. Turk

On her way to an offworld vacation, Melody Rich is violently kissed by an alien who thrusts something down her throat: the key to a lost planet. Melody's vacation becomes an adventure as she follows a map to find the solution to the alien creation she bears. After being eaten by a megabug, kidnapped by space pirates, and facing down eternity at the border of life and death, Melody comes to the end of the map. On a planet where aliens live without their heads, Melody strives to remove the key before it kills her -- again.
