Violet is off to a study course in Italy. Her mom thinks she's doing it for her university applications, but Violet has an ulterior motive. After seeing a painting of a beautiful young Italian aristocrat who could be her twin, she is determined to find out if there's a connection between them.    At Villa Barbiano, home of the summer school, Violet meets two American girls, an English scholarship girl, and the daughter of the woman who runs the program, Elisa, who resents the foreigners and undermines them every chance she gets.    Being in Italy is a dream come true for Violet, especially when she meets the dark, brooding Luca, heir to the castle on the hill--the very castle featured in the portrait that brought her to Italy. And Violet is determined to uncover its secrets no matter what the cost.
