Why I read it: Ed got got it out of the library and read it and loved it, and kind of pressed it on me. What made him so happy was the way the ending tied everything up. I bought him two other books by LMB for his birthday.
Bookmark: Library receipt.
Tastes like Chicken: I read a book a long time ago that had Crom Cruach in it, that this reminded me of. I can't remember what that book was, though, and I couldn't find it at Amazon.com. It was quite a while ago, probably 15 years. And Crom Cruach didn't come up in this book at all.
What I liked: The magic system was cool, and Ed was right -- it wrapped up nicely. The characters and their situation were interesting.
Not so much: I haven't read that much high fantasy lately. Maybe it's all like this. When I was reading, I was kind of wishing the author had found some way to set the story in a mythical Ireland or present-day something, so there wouldn't be the need for some of the world-building core-dumps.
Lesson: Really, the lesson for me was an inside-my-head editing exercise, because I was thinking about how this plotline and situation and these characters could be fit into a different world, and the story would still work. Though then it might be a different story.
