Earth’s new order has declared non-productivity a crime -- dooming Johnsmith Biberkopf to life imprisonment in a Martian penal colony. Sentenced to an eternity of never-ending toil and despair, he seeks escape in the hallucinogenic power of "onees" -- a government-banned substance that will lead Biberkopf through the portals of a strange and timeless dimension where ancient Viking ships sail the cosmos... and illusions become uniquely, terrifyingly real.

A reader's review on Amazon concludes that “It's like Sullivan tried to blend Total Recall with Fear and Loathing in Las Vegas and pulled off a halfway decent job.” A bibliography compiled by Christine Hawkins notes that the “style of this novel is reminiscent of Philip K. Dick,” whose Martian SF novel, The Three Stigmata of Palmer Eldritch (1965), also revolves around a hallucinogen.
