Onyx Storm

Onyx Storm by Rebecca Yarros
The Empyrean #3
Betrayal burns. Truth shatters. War comes on wings of shadow.
Tropes: War on the Horizon, Moral Dilemmas, Revolution Rising, Fated Bonds, Enemies Within
 
As the war against the Venin escalates, Violet faces impossible choices. The divide within Basgiath threatens to fracture everything she’s fought for, and the cost of rebellion mounts. With Xaden haunted by his past and the lines between friend and foe blurring, the storm they tried to outrun is here. Power, sacrifice, and loyalty will be tested in the fiercest battle yet—where not all will survive, and nothing will be the same.
