England, 1820. Rosalind Newbury is counting down the days until her wedding to the Duke of Marlow. She only has three weeks, and she knows exactly how she wants to spend her days. As a child, Ros created a list of 10 things to do before her wedding day. So far, she has done none of them. She enlists the help of her best friend, Liza, who brings along her cousin, Charlie. The more time they spend together, the more Ros falls in love with Charlie and his good heart. With the wedding looming, Ros must decide to either admit her romantic feelings for Charlie and risk her family's future or keep her promise to marry the duke and start a new life as a noblewoman.
