Now a single father, all he wants is to give his beautiful daughter the best life he can. Nothing, not even Leona showing up after a decade of radio silence, will get in the way of that.But Leona had her reasons for not returning. When the just-good-enough life she built in the wake of losing the baby she never told Callum about falls apart, she realizes it's time to come clean. It might be too late to keep her promise to Callum, but for the child they lost, she has to try.Faced with feelings they long thought buried, Callum and Leona have to decide if it's worth exposing all their hidden scars for a second chance at the promise of forever with the one that never should've gotten away.
