The Lost Hero, by Rick Riordan

The Lost Hero, by Rick Riordan, is a sequel of a series to the Percy Jackson and the Olympians series.  This series is called the Heroes of Olympus and has to do with Rachel Elizabeth Dare's prophecy.

Seven half-bloods shall answer the call

To storm or fire the world must fall.

An oath to deep with a final breath,

And foes bear arms to the doors of Death

It starts off as Jason, a demigod, on a bus and not remembering how he got on the bus that is going on a field trip. He can't remeber Piper, his "girlfriend" and his best friend Leo. While on the bus, Piper and Leo try to recall Jason's memeries, but they don't come back. When the bus stops at the museum, one of his classmates turns into an evil air spirit, a venti, and tries to take Jason away from the museum, and instead takes Leo, their P.E. teacher, Coach Hedge, who is their protector and savior (a satyr, but you'll have to read the Percy Jackson series to find that out) jumps on the venti and the venti, instead of taking Leo, takes Coach Hedge and dissappears with him. Then Annabeth (daughter of Athena) and Butch (son of Iris) come take them to Camp Half-Blood, where they discover their father's and mother's identities.

This book is very well written and has an amazing plot. The charactersyou love in Percy Jackson  series are also in this book. If you enjoyed Percy Jackson, you'll definately enjoy this one!!! Also, unlike Percy Jackson, the chapters change the point of view.
