Book 5 of the last triumvirate series

Reign in Chaos

Buy on Amazon


She’s his chaos. He’s the flame that could burn them both.


Raina never expected to rule Polaris. Illegitimate, half perimortal, and formerly a servant, she’s spent her life on the fringes of power. The gods, it seems, have a sense of humor, though. When circumstances necessitate that Raina is named heir to the late Lord Ursan, there’s a condition: to claim her seat, she must marry Prince Rowen, third son to the Primus of Kern.


Raina’s union to the prince, brokered by Lord Bressen, is meant to ally their countries in the coming war and secure Raina’s position against internal threats. But things aren’t that simple. The High Council of Polaris doesn’t trust Raina to rule, there’s a dangerous anti-perimortal movement ready to ignite the city, and Raina’s mother is missing, the possible victim of her pregnant stepmother’s revenge. Prince Rowen also seems to be going out of his way to make her regret agreeing to wed. It would be easy to hate him…if his smoldering touches would just stop setting her blood on fire.


For his own part, Rowen is frustrated to distraction by the stubborn, impulsive Thasian beauty he’s been ordered to marry. He was prepared for a quiet life of obscurity as the spare for the spare in the Kernish line of succession, but marriage to Raina has thrown his life into chaos. The prince isn’t what he seems, though, and the secrets he’s keeping could either bring victory in the coming conflict with Sandrian and Magdalene…or scorch the world to ash.
