Stolen Hart by E. Davies

With one look, he blew down every wall I built.
Barista Aaron Fisher has no time for shame, propriety, or boyfriends. He’s tired of being used—by his family, hookups, and even a would-be blackmailer. A year after his last heartbreak, Aaron’s ready to give love another chance. He swoops in to rescue a gentle, bashful hunky customer from the depths of app-swiping hell. Their ideas of hot dates couldn’t be further apart… but making Quinn blush is Aaron’s new favorite hobby.
After a string of failed first dates, personal trainer and hopeless romantic Quinn Powell is ready to give up on love before Aaron suggests a deal. Before December ends, can Aaron prove that great sex is all you need, or will Quinn show him that happily ever after does exist? Dating inappropriate, sassy Aaron is like sticking dynamite into Quinn’s tidy life. He finds himself remembering desires that have gone unsatisfied for years.
Before long they’re breaking the only rule: don’t hide their real feelings just to win the bet. Quinn’s afraid of scaring off the secretly vulnerable twink, while Aaron’s afraid of going tame if he gives his heart to the only man strong enough to see through his defenses. This is a lot more than a fling and a few fancy dates. But as their time runs out, they must find the strength to admit to their fears.
Both men need rescuing—but can they believe in themselves and each other when it matters most?
