A viral favorite among fans of Rebecca Yarros and Carissa Broadbent, the slowburn, high-stakes epic romantasy series continues with this highly anticipated 4th installment.

With the return of Samkiel, the rightful heir to the throne, tensions grow in the remaining realms. Battle lines begin to form between those pledging their loyalties to either Samkiel or Nismera. War looms on the horizon, and Samkiel must deal with his growing, untempered power. Without the ring of Oblivion, the dark ancient force living under his skin begins to lash out.

Meanwhile, an ancient power calls to Dianna, plaguing her dreams with messages of retribution. Samkiel, seeking to protect the woman he loves, sets out on a desperate search for answers, but the solution will mean a dangerous voyage to the one place he dares not go. The Otherworld.

Forces, primal and eternal, have taken notice, forcing Ig'Morruthens and gods to work together on a quest to reclaim an object capable of unraveling reality. An unlikely bond is formed in blood and fire, leaving all affected with no choice but one--save the realms or themselves.

It is a race against time as Nismera hunts for Vincent and Camilla, seeking what they stole. Her thirst for power and her armada only grow stronger as she rampages across the realms.

As new enemies emerge with debts of their own, demanding payment in blood, can Dianna and Samkiel find a way to reclaim the realms and his rightful throne? Or will their love burn them to the ground and consume everything they are trying to build?
