Search Worlds Without End

What would you do if you woke up and found yourself in a parallel universe under an alien sky? This is the question Zax Delatree must answer every time he closes his eyes.

Every time Zax Delatree falls asleep, he travels to a new reality. He has no control over his destination and never knows what he will see when he opens his eyes. Sometimes he wakes up in technological utopias, and other times in the bombed-out ruins of collapsed civilizations. All he has to live by are his wits and the small aides he has picked up along the way - technological advantages from techno-utopias, sedatives to escape dangerous worlds, and stimulants to extend his stay in pleasant ones.

Thankfully, Zax isn't always alone. He can take people with him, if they're unconscious in his arms when he falls asleep. But someone unwelcome is on his tail, and they are after something that Zax cannot spare - the blood running through his veins, the power to travel through worlds...

Every time Zaxony Delatree falls asleep he wakes up on a new world. His life has turned into an endless series of brief encounters. But at least he and Minna, the one companion who has found a way of travelling with him, are no longer pursued by the psychotic and vengeful Lector.

But now Zax has been joined once again by Ana, a companion he thought left behind long ago. Ana is one of the Sleepers, a group of fellow travellers between worlds. Ana tells Zax that he is unknowingly host to a parasitic alien that exists partly in his blood and partly between dimensions. The chemical that the alien secretes is what allows Zax to travel. Every time he does, however, the parasite grows, damaging the fabric of the Universes. Anas is desperate to recruit Zax to her cause and stop the alien.

But there are others who are using the parasite, such as the cult who serve the Prisoner - an entity trapped in the dimension between universes. Every world is like a bar in its prison. The cult want to collapse all the bars of the worlds and free their god. Can Zax, Minna, Ana and the other Sleepers band together and stop them?
