Rebecca Lawson is off-limits.
Jess knows this, but Rebecca has captured her heart for as long as she can remember. She's sporty, tall, and confident—all the things Jess is not—but most of all… she's her best friend Lily's sister. Nothing can ever happen between them.
Especially after that slip-up at prom night.
When Lily announces her engagement, and Jess and Rebecca are forced to spend time together as the maids of honor, the forbidden feelings intensify and sparks begin to fly.
Amidst the chaos of raging bridezillas and other wedding disasters, can Jess resist temptation for the sake of her friendship?
Or will pursuing Rebecca Lawson finally send her life up in smoke?
That Secret Something is a steamy, best friend's sister romance filled with secrets, lust, and a love that can't be denied.
