Fast Lane (Campus Drivers) by C. S. Quill

He's the campus bad boy. She's his neighbor's ex. Who thought becoming roommates was a good idea?

Lane O’Neill is living the dream his senior year of college, running Campus Drivers, the ride-share app that he launched with his best friends. The concept is simple: play taxi driver for students behind the wheel of vintage cars. The girls love it, and the four drivers are deeply committed to never disappointing their clientele.

Lane has just one rule: no attachments. Ever. After everything he’s lost, keeping his emotions locked up is the only way he knows how to move forward—seeking solace in late-night drives and the rare quiet of his apartment off-campus.

So how the hell did he end up with his neighbor’s ex, Lois Hogan, crashing at his place? She’s everything he doesn’t want—clingy, directionless, and annoyingly optimistic. The type who follows her basketball-star boyfriend to college and picks a sports therapy major just to stay close to him—then acts surprised when it all blows up in her face. Lane can’t resist calling her out on it, yet despite the constant bickering, he keeps letting her stay.

Lois thought she had her life figured out, but after a messy breakup, she’s going through a full-blown identity crisis. To top it all off, she now has to deal with an infuriatingly hot, emotionally distant roommate who seems to have a knack for driving her crazy. But Lois is done playing the good girl. If Lane wants to push her around, she’s more than prepared to push right back.
