It's all fun and games … until someone falls in love.

Oliver Goswick, Viscount Rathburn, needs money—and soon. With time ticking away and his inheritance held hostage until he's properly wed, Rathburn's slim options point to a single solution: a faux engagement. In need of the perfect bride, he knows of only one candidate: his best friend's wallflower sister. The plan seems flawless, except for one problem … He can't help falling in love with her.

Poised, polished Emma Danvers knows nothing good can come of Rathburn's scheme. Spending the next two months engaged in a mock courtship is not what she'd imagined for her final season. Yet, charmed by his roguish ways and the inexplicable hammering he causes in her heart, she accepts his challenge.

For Emma, keeping the secret seemed easy when it was just a game … But as Rathburn begins to see past her reserved exterior to the passionate woman within, the risk of losing her heart becomes all too real.
