I love this series and it just keeps getting better every book. I read this in less than 3 hours and could not put it down. It focuses on Achilles, Patroclus and Helen as they compete against many others for the title if Ares, on of the thirteen who rule the city of Olympus. I’m sure if you’re thinking of reading this book you have already read the others on the series but if not you definitely should, I guess they could be read as standalone but you will miss so much of the story and background if you skip. Also this book contains MM so if that is something you dislike you may not enjoy this, but if youre on the fence I would recommend reading it.
