I recently finished the audiobook version of Wolfheart. I thoroughly enjoyed it. 4 out of 5 stars. Based on World of Warcraft, this vast story tells of the orcs incredible invasion into Ashenvale, how the worgen came into the Alliance, a murder mystery among the elves, and KIng Varian's struggles as a king and a father. Ah, King Varian - his scenes were the best parts of the book.
