She thought the will would be simple signatures and lawyers. Instead it demands she carry an heir, and the only man who can give her one is the one she's spent years hating. Grayson Harrow has managed her family's estate since she left for college, and every terse email between them crackled with something neither would name. Now the fog has them trapped together in the main house for the fertile window the lawyers specified in clinical detail, and she has thirty days to submit to his claiming or lose everything her grandmother built. He watches her across the dinner table with the patience of a man who has waited years for her return. His hands when they finally touch her are rough from estate work, deliberate, knowing exactly how to make her beg for the thing she came here determined to endure in silence. The first time he pins her wrists and tells her she'll take him deep enough to plant his seed properly, she comes apart so completely she forgets to hate him at all. Each night he breeds her with increasing urgency as her cycle peaks, and each morning she pretends the tenderness between her thighs means nothing. But her body betrays her before the pregnancy test ever could, softening toward him, arching into his grip, whispering please when she meant to stay silent. The resentment becomes something hungrier, messier, threading through every thrust until she cannot tell where her anger ends and her craving begins. When the positive test finally comes, they have to decide whether their arrangement ends at conception or if the heat between them has built something that exists beyond the will's demands. He has filled her, marked her, made her his in the most ancient way, and walking away now would mean leaving part of herself behind. A full length novel of breeding pregnancy impregnation romance featuring a reluctant heiress, the estate manager who has wanted her for years, fertile claiming, primal surrender, and the transformation from transactional arrangement to desperate emotional need.
