Until Emma by Aspen Drake

When Sebastian James moved back to Murfreesboro, Tennessee after his parents were both killed in an accident, he stepped into a family business he never had any interest in pursuing. But he took on the new role because he wanted to take care of the people who had worked for his family for decades.
Emma White had hit rock bottom when her credit card was declined and her only source of income was delivering food to people too lazy to walk down the street and get it themselves.
While on a delivery, her luck changed and a very generous tip put her on the path toward solvency. Until her idiot brother showed up with a bounty on his head and a debt they had no chance of repaying.
Despite everything going wrong in her life, Emma finds a glimmer of hope in her relationship with a tattooed businessman who rocks her world like no one ever had before. All it takes is some trust and patience for Emma and Sebastian to realize what they have might be more than just a drop-in situation.
