Her Winter Prince

Cathryn Stewart has managed to save enough money to visit her extended family in Britain for Christmas. But when bad weather grounds her connecting flight, Cat suddenly finds herself stuck in a little country called Monteval. The only person she knows in the small kingdom is the ex-boyfriend she never got over. Luckily, there's no chance of ever seeing Anton Winter again.  

Or so she thinks, until by sheer chance, she bumps into Anton at the airport. Cat wants nothing to do with the man who broke her heart, but Anton has a proposition for her. If she pretends to be his girlfriend during the holidays, he'll get her to her family for Christmas. There's just one complication: Anton has to reveal the secret he's kept from her all these years. He isn't simply Anton Winter, the handsome foreign exchange student she dated in college.  

He's Anton von Winterhauser, Crown Prince and heir to the throne of Monteval.
