After reading this entire series myself, I have to recommend that you read the books. The books actually use modern countries like Japan and Scandinavia, then change the name and put a medieval twist on them. The rangers and their abilities are truly amazing, and the steady stream of banter between characters provide much humor throughout the books. You also learn some war strategy.

I really enjoyed reading this book just as I enjoy all Rick Riordan books, but The Lost Hero was exceptionally good in my opinion. I enjoyed the fast paced action and all of the different mythological elements that were in this book.
