1- House of Hades (10+/10)
It was the perfect book. All Tartarus parts were so good that I cannot find anything to criticize. Hazel parta were really great too and I loved Venice.
2- Mark of Athena (10/10)
Another great one. The journey from US to Rome was fantastic. We finally saw some friendship moments. Annabeth's journey and ending was epic
3- Son of Neptune (9/10)
Percy is back and it is not the best thing about the book. That's how good the book is. I am a Rome geek so Cam jupiter was a big deal for me. Really great descriptions of both environment and the camp activities. New friendships of Percy were very well too
4- The Lost Hero (7/10)
This book was good. Not great but good. Mainlyit was a starter. The problem with it was the forced romance between jason and piper (continued to be a problem for all the series but this was top) and that they were just swinging it most of the time. Still, the mystery build up was really good
5- Blood of Olympus or the book that shall not be named (2/10)
Nearly all parts (except the adventure of Nico and Reyna) were awful. And the ending was THE worst ending in fiction history. Four of the seven were forgotten. No Percy, no Annabeth, no Hazel, no Frank. Plus Jason was useless again. Leo's resurrection was not needed.
