This book is absolutely fantastic. With twists, shocks fight scenes on almost every page it is an absolute hard-to-put-down book! I read and adored the original Percy Jackson series made of 5 books, and although it doesn't seem absolutely 100% necessary to read them before this, I HIGHLY recommend that you do because it just makes this book that much more rivating. Practically every chapter had a cliffhanger, making me want to always read on without hesitation, but making me totally gutted when I had to stop. Rick Riordan wrote the novel from all three of the main characters perspectives (changing character every 2 chapters) which made this book so much more exciting as we can see and understand each character in so much more detail and really connect with them. New story, new characters, same exciting, action-packed author. The end of the book leaves us with an incredible cliffhanger that will smack your chin against your floor instantly. Extremely excited for the sequel, 'The Son of Neptune' as I'm sure it will be even more addicting, rivating, action-packed, incredible and a lot harder to put down than this one was. Magnificent book by a magnificent author. Highly highly recommend this book to anyone interested. 10*!! Enjoy.
