This is the second book of the PJO Olympians series. The second half of this book was wonderful to me. The pacing was great. I am finding myself really into the pacing of the middle-grade books that I've been reading lately. Percy's character growth in this book is insightful and causes more self-reflection. Percy seems to be thinking as a team and more cooperative in this book than in the previous book. Percy's chosen family and he seem to be working really well together. I am ready for book 3.
