At first, I thought I wouldn't like this book as much as I liked The Lost Hero due it's Roman attributes (I've always been kind of a Greek zealot) but now I stand corrected. I. LOVE. IT. Albeit it being a cliffhanger, exhilarating is the adjective to describe this book while being read. 
 As I've said in an update, Rick Riordan never lacks to provide the sensation of blowing one's mind. This is the simple yet exquisite truth. RICK RIORDAN, IF YOU ARE READING THIS, I ENJOY YOUR WRITING VERY MUCH AND IF YOU STOP, WELL, I HOPE YOU DON'T. JUST DON'T. 
 I cannot find the perfect words for the perfection of this series and the prequel of this series (Percy Jackson Series)
