The Apprentice Adept(1983)
(A book in the Apprentice Adept series)
An omnibus of novels by Piers Anthony
Apprentice Adept is a fantasy and science fiction novel series by Piers Anthony. It takes place on Phaze and Proton, two worlds occupying the same space in different dimensional planes. Phaze is a lush planet of magic, where Proton is a barren mining planet of science. As the series opens, each person born on Phaze and Proton has an alternate self living on the other world. But if a person on either world lacks a duplicate (for instance if a Proton citizen emigrated there from another planet, or a counterpart from the opposite frame died), he can cross to the other through an energy "curtain" that circumscribes each frame. The first three books in the series follow Proton serf Stile as he enters Phaze and becomes an important political force there. 1 Split Infinity (1980) The Game-champion serf Stile is assaulted on Proton by an unknown enemy, but learns he can escape into a mysterious fantasy world (Phaze). In Phaze he meets Neysa, a unicorn, and learns of his magical legacy as the Blue Adept. Back in Proton he tries to uncover his enemy, while building a relationship with his robot lover, Sheen. 2 Blue Adept (1981) Stile has gained significant power in Phaze as the Blue adept, whose songs and poems hold incredible power. However, on Proton he faces deportation and enters the tournament in the hope of gaining citizenship. His adversary is revealed to be the amulet-making Red Adept, who exists in Proton as a serf in the Tourney. Stile defeats her in combat in Phaze and in the Tourney on Proton, leading to her expulsion from both worlds. 3 Juxtaposition (1982) Years of mining for the high-energy mineral "Protonite" has left an imbalance between Proton and its sister world, Phaze. To restore the balance, Citizen/Adept Stile must juxtapose the frames and transfer "Phazeite" from Phaze to Proton, or the two worlds will both be destroyed. However, he faces resistance from the Contrary Citizens and Adverse Adepts who stand to lose considerable power if he is successful.
