If an alien passed you in the street, would you know? Except for an unfortunate attachment to numbers, Andromeda Brown is an ordinary girl with an ordinary life at a perfectly ordinary school. Until, that is, circumstances throw her into contact with folks whose zip code is, quite literally, out of this world. Her new acquaintances are in trouble and desperately need her help. They are frantically looking for a freakish, shape shifting alien scientist who has been hanging out on planet Earth for, well, ages. And hard as it is to track down someone who can change appearance at will, Andromeda's difficulties are multiplied by the fact that she and her friends are not the only ones on the shifter's trail. Darker forces are at work. For if the shifter's knowledge falls into the wrong hands, humanity is in for a very bad day.
