Santa Pongsapak is an Omega, sure-but don't expect him to swoon, beg, or submit. He's sarcastic, dominant, and completely uninterested in being claimed by any Alpha. Especially not Perth Tanapon: cold, ruthless, emotionally constipated, and everything Santa hates about traditional Alphas. But when a family-arranged bond throws them into a contract marriage, all hell breaks loose. He was never supposed to go into heat early. Perth was never supposed to fall into rut. And they sure as hell weren't supposed to mate, knot, and accidentally get pregnant. Now they're stuck with a bond neither of them wanted-but can't seem to break. And every month, biology comes back to bite. Hard.
