Summary
Mark Grayson is a rare, unclaimed omega among the Viltrumites, and he’s dangerously late for his first heat. While everyone anticipated that Nolan—his own father—would claim him, Nolan has abandoned him. Now, the empire has sent someone far more dangerous.
Conquest.
A strong alpha, feared even by the high council, arrives with a singular mission: to bond the omega before he unravels entirely. Mark is furious. Defiant. Unwilling to bend to anyone’s will. But Conquest isn’t asking for Mark’s compliance—he’s taking it.Mark finds himself trapped in a world of power dynamics he never asked for, and Conquest’s dark presence is impossible to ignore. As Mark’s heat takes hold, he begins to realize that resistance might be futile—but he’s far from submissive.
And while Mark is caught in this web of dominance and control, Nolan—imprisoned and filled with bitter regret—watches from afar. He’s consumed with jealousy, unable to accept that his son has been claimed by someone else. He’s plotting a way to reclaim what he believes is his, but Mark might not be the same boy he once knew.

Summary
Mark never expected to fall for Rex Splode, especially not after everything. But as the world burns and friends leave or die, it’s Rex who keeps showing up. Stronger. Calmer. Different. The same mouth, the same ego—but something deeper now too. Mark hates how much he needs it. Hates how Rex touches him like he owns him, like he sees through every broken piece and loves the mess anyway.

Summary
Mark Grayson lost the war. Earth is gone, and he is the prize of the Viltrumite Empire’s brutal Emperor. Not a prisoner. Not a political token. A pet. Collared. Claimed. And no matter how hard he fights, his body remembers every command. Every praise. Every punishment.
He will never be free.
And the worst part?
He’s starting to like it.
