Another great installment in the series. I had some minor issues. The person who "tricked" him was obvious. He either needs to hook-up with Granuaile or get over her. I can't take any more of him getting caught staring at her and describing the way her hair looks in the light. Oberon is still my favorite. I was in tears with his Oprah dream. I can't wait to read the next one!
