Omega’s Fight by Claire Cullen

The courtship festival has finally come to Stormshield. With his kingdom under threat, marriage is the last thing on Prince Rex’s mind. The solution? Fake a courtship to an omega prince.
Brennan, the forgotten prince of his kingdom, was banished as a child to the icy prison he calls home. When he’s offered the chance to earn his freedom, he grabs it with both hands. His task? Join the marriage circuit and destroy the kingdom of Stormshield.
When fate conspires to throw Brennan into the path of Prince Rex, he’s happy to use their fake courtship to cover his real purpose—to find and sabotage the kingdom’s magical shield. But there’s a reason why he was banished and why he’s the omega chosen for such a difficult task—he’s cursed.
The more time Rex spends with Brennan, the more he’s drawn to the omega. Brennan is the only bright spark in a month of pointless pomposity. But it’s hard to focus on matchmaking when Stormshield is in danger from persons unknown.
As Brennan’s plans come to fruition, he finds it’s not as easy as he believed to destroy those people he’s come to care for. With his freedom at stake, Stormshield’s very survival on the line, and his growing love for Prince Rex, he’s torn. Does he choose his freedom or his heart? And if he gives up his secret—his curse—his freedom isn’t the only thing at stake.
