Three Day Fiancee by Marissa Clarke

Helicopter pilot Taylor Blankenship’s time schedule is maxed out. Between his job, his one-hundred and fifty pound slobbering mess of a dog, and his matchmaking grandmother, he has no time for anyone or anything-especially a woman. If only there were a way to get Grams to back down. The job of New York City dog walker suits Caitlin Ramos perfectly while she preps for her CPA exam—steady, scheduled, and requiring very little human interaction; a huge seller since she’s still on the mend from a toxic relationship. Men suck. Especially her bossy hot client with the Saint Bernard that thinks it’s a lap dog. No way will she go for his plan to pretend they’re engaged to get his grandmother off his case. Down, boy.

Offered a bargain she can’t refuse, Caitlin finds herself playing the part of fiancée to Taylor. Fortunately, it’s only for three days. All she has to do is fake a relationship with Mr. Bossy Pants in front of his entire family, survive a fierce game of truth or dare with an unscrupulous pair of octogenarians, endure a one-on-one round of Twister with Taylor, and not lose her heart to a guy who turns out to be a lot more than she’d bargained for.
