The Chad Next Door by Dana LeCheminant

Torn between a quiet life and the chaos of unexpected love, Private Investigator Chad Briggs is set to find out if a snowstorm can melt his heart in Laketown. When Hope, the all too attractive—and far too young—woman next door, Chad’s life is thrown into a whirlwind he would rather not face, but he doesn’t have much of a choice.
Trying to navigate her new life after unexpectedly gaining custody of her dead sister’s kids, Hope knows she shouldn’t be interested in her much older neighbor, no matter how easy he is on the eyes. But when a snowstorm traps them together in one house, can they ignore the sparks between them?

With every reason to think a relationship is impossible, especially with the kids in the mix, they know a weekend fling isn’t going to end well.
