I had started this book last year when I was in my Percy Jackson kick. 
 It started off really strongly but then it got sort of slow in the middle, so I took a pause in reading this. I had gotten a little more than half-way through. 
 I found parts of it boring and I believe that's another reason why I stopped reading it for so long. 
 I was expecting the character Percy Jackson, he was not in it. However, as I got back into the book this year, I put aside what I was expecting and read it for what it was. Because this book is meant for a younger audience I had to put my myself in a younger position. Once I did that, I quite enjoyed the book. There were still points in which it was boring for me, but for the most part I enjoyed it. (view spoiler)[I enjoyed the introduction to the new characters and the different points of view. Leo Valdez was my absolute favorite! I think that it was really cool how Rick Riordan started this book off pretty much right where The Last Olympian left off. (hide spoiler)] 
 I wish that I hadn't stopped reading this and had just continued for a couple more chapters because it really picked up around page 350. I'm very excited to continue this series. I LOVE PERCY JACKSON/HEROES OF OLYMPUS SERIES!!! Honestly Rick Riordan is just a great writer!
