Love, All by Tamsen Parker

Nate Carter is living the good life. Taking a break from his engineering day job to be Camp Firefly Falls’ resident tennis instructor, he’s got nothing on his plate besides acting as best man for his sister and his BFF’s wedding, and avoiding a summer-ending injury like the one that side-lined him last year.
An unfortunate incident involving salad dressing and his tuxedo finds Nate face-to-face with struggling single-mom Ruby Hudson who’s moonlighting as a cater waiter. After their calamitous meeting, they have a far more satisfying end to their evening in the back of Ruby’s ancient station wagon.
Nate is keen for a repeat or even a relationship, but Ruby doesn’t have time for the handsome tennis player no matter how sexy his forearms are. But after convincing her to give him a shot, Nate thinks their relationship might be able to go the distance.
The end of the season is fast approaching and Nate is ready to put his heart on the line, but his assurances and their chemistry may not be enough for Ruby to upend her life. After all, in tennis love means nothing.
