Then Again, Maybe by Susan L. Tuttle

Former beauty queen Belle Thornton knows what it is to think she has it all, only to discover she never valued what was truly important. Raising her daughter and building a thriving thrift shop that helps single mothers like herself has taught Belle what the word beautiful really means. Unfortunately, thanks to her shady landlord, Belle must toss those hard-earned dollars into the money-pit of a rental that houses both her tiny apartment and her business or risk the city closing her doors. When funds dwindle as quickly as her to-do list grows, she is forced to rely on the absolute last rescuer she’d choose: Micah Shaw.
Leaving Belle at the altar, pregnant, was the worst choice Micah ever made. He returns home, hoping to reconcile with Belle and their toddler. While balancing his medical residency with caring for his ailing mother, he strives to win Belle’s heart again and ensure her business remains open. Helping with that is the easy part. Chiseling through the rock encompassing Belle’s heart is more of a challenge, but one he’s determined to conquer.
If only he could get her to realize that a new lease on love may be their best collaboration of all.
