Lexie, Dylan, and Harper have been best friends forever—with one unspoken rule: never cross that line. Never risk the friendship that's held them together through every late-night laugh, every heartbreak, every storm.

But one night of too much wine shatters the boundaries they swore to protect. A single daring kiss sparks a fire Lexie can't ignore—and Harper can't resist. Suddenly, playful tension turns into searing attraction, and their trio dynamic teeters on the edge of something entirely new.

As Lexie struggles with the weight of her feelings and the risk of losing everything, Harper is forced to confront emotions he's buried for years. But desire this deep comes with consequences. The more they give in, the harder it is to pretend nothing's changed—and the more dangerous it feels to hope for more.

With Dylan's quiet understanding offering unexpected freedom, Lexie and Harper must face the truth about what they want—and what they're willing to risk for it.

Can two best friends dare to fall in love without losing the one bond they both cherish most?

Or will crossing the line cost them everything they thought they knew?
