I wasn't sure what to expect going into this book. So many characters, I worried that it would be all about Percy and Jason and everyone else would be in the background. I'm so happy to say I was wrong. While I loved the interaction between Percy and Jason, I thought the other characters really came into their own. Piper was brilliant, sweet and strong. The relationship between Hazel, Frank and Leo was well done. The relationships between all the characters made this book great, the adventuring was in the background. Everyone learnt so much about themselves and each other, they learnt to trust one another. They are a team. It made my heart warm and fuzzy.

While this was a solid 4 stars while I was reading, I decided that once I finished this I wasn't going to go straight into House of Hades, I wanted a little break so I didn't OD on the world and characters.....
BUT.... After that ending and the tears, it moved to a definite 5 star and I'm going to get the next book, curl up in bed and probably stay up much to late immersing myself in the world all over again.
