Grace by Chika Unigwe

It is Baby's birthday, but Grace has not seen her first born in twenty-six years. Now a wife, mother to twin daughters and the owner of a successful medical clinic, Grace has carefully constructed a new life. And now, the secret she's kept for decades is about to resurface - and it could destroy everything. Grace was only fifteen when she got pregnant and, under pressure from her parents, gave Baby away. Unable to forgive their decision, she cut them off completely. Now, when Grace's estranged mother walks back into her life unannounced, the fragile existence she spent years building begins to unravel.
