Christmas at the Palace by Helen Lynch

The last thing Amanda Harte expected when she traveled to the tiny principality of Carnevale for the wedding of her best friend, Princess Lucia Alexandra, was to fall for the bride’s bad boy brother, Gaetano . But that’s exactly what happened, almost from the moment he literally ran into her as she waited for the ferry to take her to the island.
Since losing her parents in a tragic car accident Amanda, known as Mandy to her friends, shielded herself from any emotional entanglements. She was determined to never open herself off to such loss ever again. Consumed by her work she convinced herself that was enough.
Prince Gaetano, known as Luca to his friends, had his own way of dealing with loss. After he renounced the throne of Carnevale to marry a commoner, only to find out she didn’t want a prince without a kingdom and left him broken hearted and bitter, determined to play his way across Europe as the bad boy prince. No ties, no complications. Just fun.
That all changed as they were caught up in the preparations for the royal wedding and started to realize that maybe they just hadn’t met the right person. But will the pain of their past losses keep them from taking that final leap into opening their hearts?
