Vex by Kate Rudolph

He’s fire and fury. She’s the lie that could cost him everything.
Dragon Lord Vex doesn’t lose control. Ruthless, disciplined, and sworn to the crown, he’s the king’s deadliest operative and he has no patience for distractions.
Until Luisa.
She’s sharp-tongued, brilliant, and completely off-limits. But to infiltrate a criminal syndicate stealing elite identities from the Intergalactic Dating Agency, Vex has to pretend she’s his mistress.
Fake chemistry? No problem.
But it doesn’t feel fake.
The heat between them is undeniable. But Luisa’s hiding dangerous secrets, and when Vex uncovers the truth, it shatters more than their mission.
Her betrayal cuts deeper than any blade.
His silence hurts more than frostbite.
And the enemy is watching… ready to strike.
With a deadly network closing in, their only hope is each other. But can a dragon who lives by duty risk everything for a woman who breaks all the rules?
One grumpy dragon lord. One secretive human heroine. A fake relationship with scorching consequences.
