When Diana came to an abrupt stop in front of her brother, her short-cropped brown curls continued to float around her cherublike face. Her brown eyes sparkled with excitement. "Oh, Lyon, I'm so happy to see you smiling. Why, I do believe you're enjoying yourself."

She didn't wait for her brother to reply to her observation but turned to curtsy in front of Rhone. "It's so good to see you again," she said, sounding quite breathless.

Rhone inclined his head in greeting.

"Isn't it remarkable I was able to plead Lyon into coming this evening? He really doesn't like parties very much, Rhone."

"He doesn't?" Rhone asked, sounding so disbelieving Lyon actually laughed.

"Don't jest with her," Lyon said. "Are you enjoying yourself, Diana?" he asked his sister.

"Oh, yes," Diana answered. "Mama will be pleased. I do hope she's still awake when we get home so I can tell her all about tonight. I've just learned Princess Christina will be making an appearance, too. I confess I'm most curious to meet her. Why, I've heard the most wonderful stories about her."

"Who is Princess Christina?" Lyon asked.

It was Rhone who hastened to answer his question. "You've been secluded too long, Lyon, or you surely would have heard of her. Though I haven't actually met the lady, I've been told she's very beautiful. There's an air of mystery surrounding her, too. Her father was ruler of some little principality near Austria 's border. He was unseated during a rather nasty revolution," Rhone continued. "Lady Christina, if we use the title she gained from her mother, has traveled all over the world. Brummel met her and was immediately infatuated. He was the first to call her Princess. The woman neither accepted nor rejected that title."

"What happened to her mother?" Diana asked.

She looked quite spellbound by the story about the princess. Rhone smiled at her eagerness. "A tragedy, I'm told. The mother was weakheaded, and she-"

"What do you mean by weakheaded?" Diana interrupted to ask.

"Insane," Rhone explained. "When the mother learned she was going to have a child, she ran off. Until three months ago, everyone believed both mother and babe were dead."

"What happened to Princess Christina's father?" Diana asked.

"He left England shortly after his wife disappeared. No one has heard of him since. Probably dead by now," Rhone ended with a shrug.

"Oh, the poor Princess," Diana whispered. "Does she have anyone to call family now, or is she all alone?"

"For God's sake, Diana, you don't even know the woman and you look ready to weep for her," Lyon said.

"Well, it is such a sad story," Diana said, defending herself. She turned back to Rhone and added, "I remember how unbearable it was for all of us when James died. Mother still hasn't recovered. She stays hidden in her room pretending all sorts of ills, when it's truly grief that keeps her there."

Rhone took one look at Lyon 's cold expression and immediately hastened to turn the topic around. "Yes, well, we all miss James," he lied, his tone brisk. "I'm anxious to meet Princess Christina, too, Diana. No one has been able to glean a scrap of information about her past. That does make for a mystery to be solved, now doesn't it?"

When Rhone gave Diana a wink, she blushed. Lyon 's sister was still such an innocent. She was fetching enough, too, now that Rhone paused to really take a good look at her. Diana had filled out nicely since he'd last seen her. That realization actually irritated Rhone, though for the life of him he couldn't understand why. "Brat," he suddenly blurted out, "you do look pretty tonight." Rhone grimaced over the roughness he'd heard in his own voice.

Diana didn't seem to notice. She smiled over his compliment, affected another curtsy, and said, "Thank you, Rhone. It is kind of you to notice."

Rhone frowned at Lyon. "Her gown is cut entirely too low. What could you have been thinking of to allow her in public this way? You'd better keep a close eye on her."

"If I keep my eye on you, Diana will be safe enough," Lyon answered.

"All the same, I really think…" The sentence trailed off, for Rhone had just glanced toward the entrance of the salon. He let out a low whistle. Diana quickly turned around to see what held Rhone so enthralled.

"Princess Christina." Diana whispered the obvious, her voice filled with awe.

Lyon was the last to react. When he saw the vision standing across the room, he literally jerked away from the mantel. His body instinctively assumed a battle stance, his muscles tensed, ready.

He was slow to regain control. He realized his hands were actually fisted at his sides and his legs were braced apart for a fight, and he forced himself to relax. The abrupt movement made his knee start throbbing again. Lyon couldn't do anything about the pain now, or the furious pounding in his chest.

And no matter how valiantly he tried, he couldn't seem to take his gaze away from the Princess.

She really was lovely. She was dressed in silver from head to toe. The color belonged to an angel and highlighted the paler threads of her blond hair.

Without a doubt, she was the most beautiful woman he'd ever seen. Her skin appeared to be flawless, and even from the distance separating them Lyon could see the color of her eyes. They were the most startling shade of blue.

Princess Christina neither smiled nor frowned. Her expression showed only mild curiosity. The woman obviously understood her own appeal, Lyon concluded, hoping his cynical nature would save him from heart failure. He wasn't at all pleased about the way his body continued to respond to her.

"Brummel was right," Rhone announced. "The lady is enchanting."

"Oh, I do hope I'll be able to meet her," Diana said. She whispered as though they were in church. "Just look at everyone, Rhone. They are all taken with her. Do you think the Princess will be agreeable to an introduction?"

"Hush, Diana," Rhone said. "Princess Christina wouldn't dare ignore you. You seem to forget just who your brother is."

Diana gave Rhone a timid nod. "Sweetling, straighten your shoulders and quit wringing your hands. You'll give yourself spots. We'll find someone to give us a proper introduction."

Rhone knew Lyon 's little sister hadn't heard the last of his remarks. She'd already picked up her skirts and headed for the entrance. "Now what do we do?" he asked when Lyon grabbed hold of his arm to stop him from chasing after Diana.

"We wait and see," Lyon advised. His voice sounded with irritation.

"Your sister is too impetuous," Rhone muttered, shaking his head. "She's ignoring all her lessons in-"

"It's high time Diana learned the lesson of discretion."

"Let us hope it isn't too painful for her."

Lyon didn't remark on that hope. He continued to give his attention to the beautiful Princess. An elderly couple approached the woman just as Diana came barreling to a halt a bare inch or so in front of them.

Diana almost knocked Christina to her knees. Rhone let out a long groan. The elderly couple didn't even try to hide their displeasure when they were so rudely cut off. Both turned away, staring at each other in obvious embarrassment.

"Oh, God, Diana just cut in front of the Duke and Duchess," Rhone said.

Lyon was infuriated with his sister. He was about to go after her to save her from further humiliation when the Princess took matters into her own hands. Rather nicely, too. She greeted Lyon 's sister with what appeared to be a sincere smile, then took hold of Diana's hands when she spoke to her. Lyon thought the Princess was deliberately giving the impression to all those watching that she and Diana were close friends.

He watched the way Christina motioned Diana over to her side so that both could greet the Duke and Duchess of Devenwood. The Princess included Diana in the brief conversation, too, effectively smoothing over the mistake his sister had made.
