Something to Someone by Grace Turner

She’s eleven years older and all he’s ever wanted. Oh, and his mom’s best friend.

With college graduation imminent, Ryder Calaway is only looking forward. A new job and a new apartment are on the horizon, but his version of the future also includes Caroline Grant—the woman he’s been pining after for eight long years and his mom’s best friend.
But Caroline is more focused on running her business than she is with her love life. Actually, she can’t even say the word “love” without cringing. Men are great for a night, but nothing more. It’s a rule that’s protected her once-broken heart and one she doesn’t plan to break.
Until an unexpected run-in with Ryder leaves her flustered. She’d guessed at his feelings—at his crush—but finally, he admitted in no uncertain terms that he wants her. And in the heat of the moment, she unwittingly confesses that the attraction isn’t one-sided.
Still, Caroline isn’t willing to bend her rule. But Ryder wants her anyway. Whatever she’s willing to give, he will humbly and eagerly accept. Making it impossible for Caroline to resist.

Because none of the reasons why it’s wrong make a difference when it feels so right.
