Question of the Week - What did you think of the last Heroes of Olympus book?

I personally loved about 90 percent of it, the final battle was awesome yet kind of a letdown because the final solution was kind of telegraphed before hand. Saying that though I still like the endings that you see for the characters/what you can infer their lives might end up like. I just wish the last chapter had been elaborated on more and well when it ended I was looking for more story...
