Mackenzie is my best friend's little sister. Off-limits in more ways than one. But I spent my football career bending the rules... and she's too tempting to resist. I should know better than to fall for Mackenzie Cavanaugh. She's the one who got me hooked on romance novels in the first place, and it should have been clear when my favorite stories revolved around the "best friend's little sister" and "dating in secret" plot lines... But I've read enough of these stories to know it doesn't usually turn out so well. Mackenzie isn't just Miles's sister, though; she's my friend in her own right, and her overprotective brother's objections shouldn't be enough to keep us apart. No mater how much he tries. My football career is over, so now the rest of my life can begin. My focus has pivoted from surviving every day to thriving in real life. At the end of this school year, I'm going to pick up and move across the country for grad school-where I'll end up, I'm not sure, I just know that it probably won't be here. FUMBLE is a college sports romance best friend's sister romance featuring a secret relationship, two introverted bookworms, a virgin heroine, and a celibate-by-choice football player.
