This sequel to The Hollow Kingdom was entertaining enough, but I found it overall to be rather disappointing. There were definite high points: the fleshing out of the history of the conflict between the elves and the goblins was welcome, and Dunkle's depiction of the dying elf culture was excellent, if harsh.
There were quite a few problems with the book, though. For one, the pacing and plotting was very odd; I felt that Dunkle introduced a lot of plot elements and then didn't give them their due, and the story seemed to move in fits and starts.
I also, quite frankly, had problems with Dunkle's handling of the characters in this one, particularly the women. Kate was so fantastic in the first book, and Sable, a young elf woman, had great potential to be just as interesting. Dunkle never really lets that potential play out, however, and after a daring act at the beginning of the novel, Sable fades into little more than a passive pawn. Dunkle's characterization of Irina, the other elf maiden, was downright forehead-slappingly offensive; the character is completely, unbelievably vapid. There's an attempt toward the end to make her more than a pretty cardboard cutout, but by then the damage is already done.
Finally, it bothers me that the author has created a sympathetic culture (the goblins) who rely on wife-stealing to further their race, and has really just completely failed to truly explore the ramifications of this. There are attempts to do so, but for all of the main characters it pretty much boils down to a kind of Stockholm Syndrome, where the stolen wives decide that they are better off where they are now. I might even be ok with this if it was more blatantly acknowledged, but instead it feels like Dunkle is glossing over something uncomfortable that she herself has created.
