The Althusians crash-landed on Earth deranged and confused. Hyperspace travel had stripped away their memories and their very identities. They were eventually assimilated into human society, but they had vast holes where memories should be. They took menial jobs like washing dishes and sweeping floors and driving cabs. All seemed well until a rumor started going around that these amnesiac aliens had the ability to warp time. Then one day a lovesick man named Gary slid into the backseat of a cab driven by an Althusian and learned that the rumor was true.
Blue Devils is an enjoyable quick listen, with mainly 2 good characters, good storyline with the ending throwing you for a loop, Good narrating job by Theo Holland. I received this audiobook free and I am giving my voluntary unbiased review.
