Split Infinity (Apprentice Adept #1)
SF can be tricky stuff, particularly when you start reaching for books that were printed more than a decade ago. Some books just age well, some just look like giant piles of stinking poo. Split Infinity, written more than 25 years ago, has aged well. The lumping together of Science Fiction and Fantasy can be frustrating to fans of one genre or the other, but this books manages to span the two genres.
We are introduced to Stile, who is a serf on the SF world of Proton. Due to a number of various issues he literally stumbles across to the Fantasy world of Phaze, where he uses the various skills he acquired on Proton, and a lucky dose of magic, to learn more about the world. Along the way we learn the back story of Stile, his training and history as well as more information about the Phaze. Stile is fantastically lucky with the ladies, he seems unable to enter situations where at least one woman doesn't become enamored with him. As well, Stiles also appears to be among the most powerful of Phaze, an Adept, with ready access to magic.
A great story as Stile meets unicorns, robots and werewolves and continues to "know thyself" as well as balance his life in both worlds.
