Children of Fallen Gods (The War of Lost Hearts, #2) by Carissa Broadbent

No war can be fought with clean hands. Not even the ones waged for the right reasons. Not even the ones you win.

Tisaanah bargained away her own freedom to save those she left behind in slavery. Now, bound by her blood pact, she must fight the Orders' war -- and Max is determined to protect her at all costs.

But when a betrayal tears apart Ara, Max and Tisaanah are pushed into an even bloodier conflict. Tisaanah must gamble with Reshaye's power to claim an impossible victory. And Max, forced into leadership, must confront everything he hoped to forget: his past, and his own mysterious magic.

All the while, darker forces loom -- far darker, even, than the Orders' secrets.

As Tisaanah and Max are ensnared in a web of ancient magic and twisted secrets, one question remains: what are they willing to sacrifice for victory? For power? For love?
