Her True Alpha by Isoellen

Phee was a proper Omega.
She’d done everything society expected of her–Obeyed her parents, married an appropriate choice of Alpha, tolerated his infidelity.
And what was her repayment? To be cast out by her husband in favor of his pregnant mistress.
With their marriage contract canceled and her reputation in tatters, Phee’s future seems hopeless.
Then, the most unexpected suitor appears… Right as her long-absent heat begins.
