The story picks up at kind of an odd point and ends with an odd guest showing up. Leo and Calypso are still together and figuring out how to make their relationship work, while on a mission. Lester/Apollo is still trying to become his godly form again. All three stumble into the Waystation and the adventure starts there. Immortals from Apollo’s past show up and the chaos ensues. Meg becomes part of the group again and her powers are improving. Apollo who wants to see the good in people, brings some questionable members to the Waystation and the rag-tag team is held together by the bonds of being an outcast.
Rick Riordan as always does a great job of weaving the mythological and modern society together to create this adventures. The new creatures that make appearances in this adventure are heartbreaking and scary. The joy of the victories are dampened by the losses that occurred. The reality of battle is shown in this book while showing how the ones who survive cope with the lose of those who did not. Riordan is able to incorporate the sadness, hate, and woe in the world today, while showing happiness is possible if you search for it, love can be found if you look for it, and friendship is what makes the impossible possible.
