I grew up with this book series, and ive always loved reading. Plus Rick riordan is my favorite author and the heroes of Olympus and Percy Jackson series are my favorite books ever. I've spent all day attempting to buy the blood of olympus but with no luck. I really love this book series and really want to read this book. I've read every book starting from the Lightning thief to the house of hades. I've even read the staff of Serapis and the son of sobek.
