amazing book I loved it !!
before reading this book you should read the other two !
• this is a non spoiler review
there are 7 main characters : Jason/Percy/Piper/Leo/Frank/Hazel/Annabeth
side characters (but still important ) : Couch Hedge/Nico Di Angelo/Reyna/Octavian/Dionysus/Hercules...(can't remember the others )

I can't really review it without spoiling the book 1 and 2 but in the end when I finished the last Chapter I was alone at home and for a hole 8 minutes I was digesting what i just read I was literally shocked and impatient to buy the 4th book : the house of Hades

this is emotional but not to the extreme
I was forced to read this book for the British Council but I ended up liking it a lot !!!!
this story is about a boy named Cameron he is a African-American and he has heart problems ... I think he has 1 month or 2 to live before his heart stops working . BUT one day his father contacts a doctor that can help him but it will be risky ... and so this story follows Cameron and his decisions to become healthy again!

sorry if the review is rubbish i'm new and I don't actually know how to review so... yeah
