Space Hippie

What if a mad scientist wants to destroy all life in the Universe, and the only people who can stop him are... a camper bus full of hippies? Join our tree-hugging, drug-free heroes as they zoom across galaxies in their solar-powered bus. Will they defeat the greasy villain in time? And do they have enough veggie burgers to make it to the next planet? For readers ages 11 to 111.
