Promised to the Alpha Prince by Jove Chambers

The marriage was arranged when Aurelie Le Blanc was a child. On the several occasions she’s met Prince Dmitri Klein of the country of Valhn, he’s been cold, distant, dismissive.

Of course, she’s never expected love, not as a royal omega. She’s marrying him for duty and appearances, nothing more.
He doesn’t even come to fetch her himself. He sends Prince Johannes Fischer, next in line to the throne of Valhn, and some commoner companion, Nikolai Wolff, who looks her over with a lethal leer. At least Prince Johannes is charming and easy to be around. He assures her that after her consummation with Prince Dmitri, she’ll be allowed other alphas to ease her omega needs, and Prince Johannes is enthusiastic, eager to be there for her. It’s nice to be wanted by someone.
But she can’t be with Prince Johannes yet (or Nikolai—apparently, they’re a matched set, not that she minds), not until she is officially married and mated to Prince Dmitri, who never seems to want to spend time in her presence.
It’s shocking, then, when she goes into heat, and he’s all she needs. It’s molten, possibly the most erotic experience of her life, a passionate pinnacle that undoes her. His knot, his bite, his body…
She’s fallen for him.
Which is exactly when her childhood friend and adolescent sweetheart, Corentin Sejour, reappears. Now, somehow, he’s an alpha. She swore to him once, when they were very young, that she’d never love anyone the way she loved him.
But she can’t run away with him now, no matter what she promised then…

RH contemporary omegaverse with drama galore, and very jealous, possessive alphas.
