Althea is the source of piezo-temporal crystals, which distort time and make interstellar space-flight possible. The Company has a monopoly, but when aliens show up to do a little mining of their own it spells big trouble. Twenty-three year-old mechanical engineering technologist Mickey and his friends race against time to save the others, foil the aliens and win their freedom.
