Vision in White by Nora Roberts

Roberts' first book in the Bride Quartet begins a new series about four childhood friends who grow up to start a wedding business together. Mackenzie Elliot throws herself into her photography to distance her heart from her mother issues and the abandonment of her trust-fund father. She is pursued by Carter Maguire - a stable PhD in English who had a high school crush on Mac. Carter tries to help Mac see that life can be just as wonderful untouched in the darkroom and even if it is unfocused and messy - it's always better with someone who truly loves you.
