Harper Quinn never planned to fall for anyone when she moved back to her sleepy hometown—especially not the one man she's sworn off limits since high school: her best friend's older brother. But Drew Maddox isn't the lanky guy she remembers. He's a confident, broody firefighter with a soft spot and a smirk that makes her question every boundary she's set.

Living under the same roof, Harper and Drew try to play it cool. But close quarters and old sparks quickly reignite, turning casual glances into lingering touches—and unspoken feelings into something neither of them can ignore. The only problem? Maddie. Harper's best friend. Drew's fiercely loyal sister. And the one person who made Harper promise not to cross this line.

Caught between friendship and a love that feels inevitable, Harper must decide if risking everything is worth a chance at something real. But when the truth comes out, hearts are broken—and the future they both imagined might shatter before it ever begins.

Can love survive the fallout of loyalty and betrayal?

Or will breaking the bestie code break them apart for good?
