Date Bloomer by Diane Michaels

Paloma Blumenthal is contentedly staring down forty. Thanks to her thriving flower shop, a city full of friends, and even her ornery cat, she wants for nothing, least of all a man.
So why, after an evening of kissing Sam Barnes during a trip to the Catskills, does her heart beg for more?
The bed of roses she had left in New York City turns to compost upon her return. Between disgruntled clients, an over-active parking enforcement officer, and an unwanted visitor, the lure of the small town of Jimmy Creek and the new romance it promises become impossible to ignore.
Unfortunately, so does Sam’s age.
Falling for a younger man goes against her better judgement. But when it comes to love, she might be the one who still has room to grow.
