Vortex (Insignia, 2)

S. J. Kincaid has created a fascinating dystopian world for Insignia, her futuristic science-fiction adventure series perfect for fans of Ender's Game. Earth is in the middle of WWIII, a war to determine which governments and corporations will control the resources of the solar system.

Teen Tom Raines grew up with nothing—some days without even a roof over his head. Then his exceptional gaming skills earned him a spot in the Intrasolar Forces, the country's elite military training program, and his life completely changed.

Now in Vortex, the second book in the series, Tom discovers that the Pentagonal Spire, where he and his friends are being trained as superhuman weapons, is filled with corruption. He is asked to betray his friends—the first real friends he's ever had—for the sake of his country.

Will he sacrifice his new life to do what he believes is right?
