Lunch and Love: The Cowboy and the Princess by Lori Wilde

On the run from an arranged marriage, Princess Annabella of Monesta dons the guise of a hitchhiking cowgirl. But when she finds herself drenched, alone, and hungry, she has no choice but to trust the tall Texas horse whisperer who offers her a ride. He's like no one she's ever known—a strong sexy man who says just what he thinks. And when one wild kiss leaves her breathless, she quickly realizes she'll give up everything to spend a lifetime of night times in his arms. But how can there be happily-ever-after with palace guards hot on her trail?
