Here is kind of a off the wall one. how about some of the shadow run novels.
the rpg is based around a future that has brought use of magic back to the world and modern day humans change into trolls, orcs, dwarfs, and elfs. hear the books are all very good(few that I read are) but Im not sure that they sell them in ebook format so maybe this does not work .
was planing on making a more detailed lookup of them when I get a reader.
