The Ex Effect by Dana Hawkins

Morgan Rose has always been the girl with the plan. Color-coded calendars, backup plans for her backup plans, and a wedding business that’s her entire world. Only one woman ever managed to derail Morgan’s organized life and shatter her heart in the process. But Morgan doesn’t think about Frankie Lee anymore.

Until Morgan meets the photographer hand-picked by her latest clients and discovers that Frankie is not miles away in New York like she thought. She’s back in Spring Harbors, looking infuriatingly good, and Morgan’s carefully ordered world descends into chaos.
Morgan has just 87 days to pull off the wedding of her career and she’s not going to let Frankie derail this opportunity. She will not be distracted by Frankie’s new haircut or the shadowy dips between her shoulders and biceps. And she won’t care about Frankie’s unfairly salty attitude when she left Morgan.

But some sparks never die, and as the wedding approaches and the tension between Morgan and Frankie grows, can they face up to the mistakes that pulled them apart, or risk it happening all over again?
