This is definitely my favorite of this group so far. The author brings together the characters of past adventures, with their histories from other stories, combined into an action-packed story. Perfect for young readers, or young at heart, the book pace never languishes, yet speeds ahead, with ample humor and wit. I also appreciate the clean writing this author brings to his stories as well, which is unfortunately a rarity in today's publishing world. Rick Riordan has certainly built a level of trust into his readership, as well as a remarkable set of stories for all to enjoy.
