I bought this book by mistake, thinking it was a mystery by a similarly named author---but it's a darned good light romance!
From back cover:
Knight in shining armor . . . or avenging angel?
Five years ago Luciano de Valenza had rescued the Linwood family's failing wine business. In the process, he'd swept young, impressionable Kerry Linwood off her feet. But shockingly, when money was embezzled from the business, Luciano had found himself convicted and imprisoned.
Now he was free, and back to clear his name. He was sure he'd been framed by the Linwoods, and he wasd determined to take all that was theirs. That included Kerry. Kerry---who was now convinced Luciano desired her only for the wine empire she would inherit. Kerry--who couldn't understand that SHE was all he had ever really wanted.
