Middlegame (The Amnesty Games #2)

Along with Nico and their two fellow fugitives, Alora seeks refuge deep inside the devastated Ward. Pursued by the Finest and mistrusted by the Warders, she is forced to run for her life. Her search for safety and answers is complicated by the Prodigies, a rogue band of techno-genius mercenaries with the power and the desire to start a war.
And they plan to use Alora and Nico to make it happen.
