"The Lost Hero", Rick Riordan (YA-Fantasy)

"The Lost Hero" continues the storyline of Rick Riordan's "Percy Jackson and the Lightning Thief" series, but with a twist.  In this story arc, we are introduced to three new demigods, with splashes of the ones we're already familiar with.  These heroes are also at Camp Half-blood and we visit several Greek gods.  However, these Greek gods tend to morph into their Roman counterparts when in the presence of Jason.  Jason is leading his friends on a new quest to save the world, only he has no memory of his past.  Piper and Leo are 2 other demigods who will form the seven needed.  One question remains until the end of the book...where is Percy?

I rather enjoyed this new story arc.  Of the Percy Jackson series, I only read the first volume.  This one seems to be written better than the previous series.  It was a quick read and I am interested in the rest of the series.  I gave the book to my son (13 years old) and he devoured it in one day, which is a ringing endorsement.  This would be a great book for middle school students or advanced readers in upper elementary.  I purchased one copy for my K-6 school library and many of the 5th and 6th graders are chomping at the bit to check it out.  There are some battle scenes, but no profanity and no sex.
