I know I am giving up all of my GoodReads cred by saying this, but I liked this book a lot. To repeat my review of _BaneWreaker_, this is a well done Sauron apologetic which re-arranges the original story in interesting ways while still managing to be its own tale.
As a small example, take the cover page of the book. You have your generic fantasy title, which ends up referring to something completely different than you would think. You have a noble white stallion (a Shadowfax analog), which used to be our protagonist's favorite horse, until Gandalf stole it and brainwashed it. And then you have the Gandalf-analog, who is a complete ass. He is like the snooty, too-perfect British suitor in a Rom-Com; there is basically no scene where you are not rooting for him to get stabbed.
This book isn't on the same level as Beowulf/Grendel, but it is still a fast-paced and enjoyable read that manages to turn its fantasy-cliche vices into virtues.
