Rebels: City of Indra

Lex grew up in the orphanage, alone, and now is training to be a Special Op so she can finally destroy the rebels with her own hands. She needs no one. Livia lives miles above everything on a floating island in the city of Indra. She is training too, but for a life that she doesn't want. She wants to be free, to finally leave her floating island, and to run with her beloved horse until she can't run any longer. And then there's Kane--Lex's only friend. When she finds that Kane is in danger, she doesn't hesitate to leave her post and blast her way to the top of Indra to save him. She just needs to get one stubborn, unexpectedly clever airgirl to tell her where he is first.
