Appraised

He's a widower trying to raise his rebellious teenaged daughter ... She paid a guy in Vegas to teach her how to enjoy sex after her divorce.

Sawyer Callahan is a total silver fox, complete with a sad backstory and a near obsession with budgets, spreadsheets and tidiness, who happens to be a real estate appraiser. When he accidentally spills a beer down Miranda's blouse at a bar, he offers his shirt as a replacement, then bolts before she can properly thank him.
Successful real estate agent Miranda is more than a little obsessed by the grey-haired stranger but she's busy planning her forty-fifth birthday trip to Vegas to meet up with her once-a-year boyfriend. When an appraisal on one of her listings comes in low threatening the deal, she finds herself facing off with the appraiser—none other than the handsome guy with the glasses and sad eyes who ruined one of her best blouses.

Things get even more complicated when he asks her to list his house. Now Miranda has to decide between her Vegas boyfriend who offers her an engagement ring for her birthday, and the somewhat nerdy man who offers the sort of emotional support she thought she didn't need anymore.
