This book is a fast read that will make you want to re-read it over and over. I was fist introduced to this book by a friend. Firstly let me point out i am not the reading type, however this book had me hooked i couldn't stop reading it (I've missed quite a few stops on the bus because of this book).
Piers Anthony has created a wonderful world (or worlds should i say) in which Stile (the main character) is a minor inhabitant he is a jocy on a planet called proton until it all goes pear-shaped when there is a threat on his life.
The title 'Split Infinity' makes more sense after you've read the book. Piers has two worlds which are parallel dimentions on is Proton and one is called Phaze. Proton being the futuristic planet barren out side bio-domes, and Phaze being a lush land of magic and mythical creatures.
All in all this book is an amasing read it totaly pulls you in and you won't want to put it down and you be sad to when you've finished.
BTW: Split Infinity is number one in a series to find the others go to amazon.com and serch for The Apprentice Adept Series, for a full list; as some of the books are not avalible in the UK or are out of print (however lots of second hand copies on amazon.com and .co.uk for that matter)
