I'm so glad I read this series. It was super entertaining and sweet. I loved Annabeth and Percy. I loved Grover and Tyson. I loved Sally, Paul and Poseidon. I loved the relationships between the various gods. Look I had a lot that I loved about this series. Yes it got a little prechy at times but it's also for a much younger demographic than I fall into so I can forgive that. 
 I thought the way everything wrapped up was a little too neat, but again way outside of the age demographic, that being said I liked how it's not super obvious how it was going to wrap up. However I called the thing with Rachel pretty early on. 
 Anyway I put the next series on hold and am just waiting for The Lost Hero to become available.
