Morning Star by Pierce Brown

The conclusion to the "Red Rising" trilogy (tears because it is ending) is just as action packed and full of surprises as the first book.  Futuristic space world mixed with ancient warrior Roman and Scandinavian Gods where an elaborate class system is under attack.  Those who start on the bottom will always want to take down those on top but now Darrow must decide where his loyalties lie.  He is cast as the Savior for the low colors but struggles going against the people he has grown to admire and fought battles with.
Wonderful rich characters, blow by blow battles scenes delivered with razor-sharp wit keep you off balance, out of breath and racing through the book to the conclusion.  Ready for the movie? It will be epic. This series is for adults but teens will devour it.
