I'm just on a Rick Riordan kick and I could read his books all day. 
 I started this book immediately after finishing the Percy Jackson series. I NEEDED more Percy Jackson. Did this book give me that? Nope. But, this series will. I liked the format of this book with the three different view points of Leo, Jason, and Piper. I liked the characters, although some reviewers have stated that they lack in comparison to Percy, Annabeth, and Grover. But, these characters are already teenagers and I enjoyed that they were the same age as the characters that we know & love. 
 I was really interested in reading about the Greek vs. Roman sides of the Gods. Mythology is definitely an area that interests me, and I appreciate that Rick is creating this story to combine them into an epic adventure. 
 That ending though. I did sense it coming, just because it seemed like that would be the case. It definitely made me really excited for book #2!
