Family is everything - Grace McAdams's mom must have said it to her a thousand times before she died. Before Grace's dad ran off with an aspiring actress half his age. Before only-child Grace found out she was unable to have children of her own. Before Brian - her childhood best friend, business partner, and finally her husband - dropped a 'bombshell' on her in the form of her stunning new replacement. Which means Grace now has - nothing. Until she receives a letter from a woman claiming to be a relative Grace never knew she had, sending her on a journey from the childhood home she had to move back into, to a Florida island to meet a total stranger who embraces her as family.
