From Enemies to I Do by Rachael Thomas

When her enemy…
…becomes her groom!

Sienna Hamilton refuses to marry Italian playboy, Rico Marchetti—especially after he humiliated her all those years ago. Yet the terms of her stepfather’s will are clear: marry Rico before Christmas Eve or forfeit her hard-won share of the family business. The answer seems simple, but there’s more at stake than just her inheritance. When it comes to Rico, Sienna knows the bigger risk is to her heart…
Rico will do anything to reunite the company his uncle so hastily bequeathed to his stepdaughter. But marriage? Rico’s seen martial destruction first-hand and is determined to avoid the institution. A temporary arrangement is much more agreeable. But his meticulous wedding contract doesn’t account for the intense desire he feels at seeing Sienna again. Suddenly, there’s more to lose than Rico ever thought possible…
Can Sienna and Rico forgive the past in favour of a future—together?
