The Hammer of Thor

Although Rick Riordan eased up on all the Percy Jackson allusions (my blood pressure thanks ye), that ending...it...it was so...AKSEILDFHAGSKDHFLJAHSGJDFKLASDF. I think it's safe to say that the ending was my most favorite part of the whole book. The contents weren't terrible or anything. And there were certainly plenty of adrenaline-pumping adventures to spare. However, none of that compared to the shock I received upon...that fated ending.
