The Heroes of Olympus Series: Books 1-4

By: Rick Riordan

This series follows Riordan's Percy Jackson & the Olympians series.  The author introduces many new characters but weaves their stories to include the main characters from the original series.  One of the biggest challenges is that a Roman group of demigods is discovered - and they consider the Greek demigods their enemies.  However, to save the world, these two groups will be forced to work together and trust each other.

Mrs. Senechal says:
I almost enjoyed this series more then the first!  I love all the new characters, and I continue to learn a lot about both Greek and Roman mythology.  In typical Riordan style, there is plenty of action and suspense.  There is one book left in this series - to be released in October 2014 - and I can't wait to read it!

The Last Olympian

By: Rick Riordan

In this, the fifth and final book of the Percy Jackson series, Percy and his friends find themselves in their most difficult battle yet. Instead of just fulfilling quests or defending themselves against monsters, the fate of all the gods lies with them. In New York City, Percy, Annabeth, Grover, and Thalia must keep the Titan forces away from Olympus (secretly situated above The Empire State Building). Each of the young heroes will be forced to make difficult decisions and make some incredible sacrifices if they are to succeed.

Mrs. Senechal says:

In an earlier post, I share how much I loved the first four books in this series, and the fifth book does not disappoint! The action starts in the first chapter, and the suspense lasts until the last chapter of the book. I liked how the author tied together pieces from the previous books, and how he developed the characters throughout the series. This is one of the most exciting book series I've read in awhile! Start with the first book, and you'll be hooked for all five!
