Send Sunshine by Heather MacKinnon

Can her light overcome his darkness?
Bailey Woods is perfectly content living the single life. After being disappointed by men one too many times, she completely gave up on dating. Until she volunteers to spend time with a lonely horse and winds up working with the surliest man she’s ever met. So, why can’t she stop thinking about him?
Ryder MacAlister has three rules: no girls, no mistakes, and no slowing down. And Bailey is about to make him break all three. From the moment he met her, he felt this undeniable attraction. Fighting it is pointless, but he knows he needs to keep his distance. His past is as sordid as his future and he can’t let anyone else get mixed up in his problems. Especially Bailey.
She can’t resist a challenge and is determined to break down his walls for a single night. But what happens when she sees behind his gruff facade? Will Ryder’s past prevent a future with Bailey? Or could she be what he’s needed all along?
