I really enjoyed this book. Riordan peppered a great plot with fantastic psychosocial commentary about youth homelessness and technology in culture. Very well done. I love watching how the gods of ancient cultures are modernized in his work and, while Percy Jackson's books remain my favorites by Riordan, this book was fantastic and I cannot wait until the next one.

Edit to add: Having just finished the book for the second time, this time 2 years after my mother died unexpectedly and suddenly, I have to say Riordan writes grief really well.
