Banewreaker: Volume I of The Sundering

Much darker than Carey's "Terre d'Anges" series, this series (without explicitly mentioning it) presents the story of Lord of the Rings from the viewpoint of the other side. Not that the characters or the places have the same names, but the similarities are made obvious enough for the reader not to be in any doubt, The story is considerably changed (otherwise it would be a rather boring book), so Banewreaker in part is based on The Hobbit and part on The Fellowship of the Ring.

And much better written than Pullman.
