This one has an interesting history. Feist's Riftwar series was licensed for a famous
MS-DOS game in the 90's. The game was widely praised at the time for its characters and writing, which were assumed to be written by Feist himself, but in fact were written by the game's development team.
Feist
did, however, pen this novelization of the game some time later. Not having read it, I am unable to weigh in on whether the book was better.
