"Alone?"

"Of course," she said, surprised. Did he think she'd hidden a passenger in the trunk?

Cash said something sibilant and succinct. He backed out from beneath the hood, wiped his hands on a greasy rag and glared at the filthy engine; but he was seeing Mariah's lovely, uncertain smile, her clean-limbed, sexy body and her haunting aura of having been hurt once too often. He guessed that Mariah was a bit younger than his own sister, Carla, who was twenty-three. It made Cash furious to think of a girl who seemed as vulnerable as Mariah driving alone in a totally unreliable car from Seattle to the Rocking M's desolate corner of southwestern Colorado.

Cash took the weight of the hood from Mariah's hands and let the heavy metal fall into place with a resounding crash.

"What in hell were you thinking of when you set off across the country in this worthless piece of crud?"

Mariah opened her mouth. Nothing came out. She had driven the best vehicle she could afford. What was so remarkable about that?

"That's what I thought. You didn't think at all." Disgusted, Cash threw the greasy rag on top of the useless parts. "Well, baby, this wreck is D.O.R."

"What?"

"Dead on Road," Cash said succinctly. "I'll tow it to the ranch house, but the only way you'll get back on the road is with a new engine and you'd be a fool to spend that kind of money on this dog. From the wear pattern on the tires I'd guess the frame is bent but good. I know for damn sure the body is rusted through in so many places you could use it as a sieve. The radiator is a sieve. The battery is a pile of corrosion. The spark plugs are beyond belief. The carburetor-" His hand slashed the air expressively. "It's a miracle you got this far."

Mariah looked unhappily at the rumpled sedan. She started to ask if Cash were sure of his indictment, took one look at the hard line of his jaw and said nothing. Silently she watched while he attached her dead car to the Jeep. In spite of her unhappiness, she found herself appreciating the casual strength and coordination of his movements, a masculine grace and expertise that appealed to her in a way that went deeper than words.

Unfortunately, it was obvious to Mariah that the attraction wasn't mutual. After several attempts, she gave up trying to make small talk as she and Cash bumped down the one-lane dirt road leading toward the ranch house. Rather quickly the wind pulled apart the knot she had used to confine her hair. The silky wildness seethed around her face, but she didn't notice the teasing, tickling strands or the occasional, covert glances from Cash.

Mariah's long trip from Seattle in her unreliable ear, her disappointment at not seeing Luke, her attraction to a man who found her aggravating rather than appealing – everything combined to drain Mariah's customary physical and mental resilience. She felt tired and bruised in a way she hadn't since her mother had died last year and she had been left to confront her stepfather without any pretense of bonds between them. Nor had her stepfather felt any need to pretend to such bonds. Immediately after the funeral, he had put a frayed cardboard carton in Mariah's hands and told her, Your mother came to me with this. Take it and go.

Mariah had taken the carton and gone, never understanding what she had done to earn her stepfather's coldness. She had returned to her tiny apartment, opened the carton, and found her MacKenzie heritage, the very heritage that her mother had refused ever to discuss. Holding a heavy necklace of rough gold nuggets in one hand, turning the pages of a huge family Bible with the other, Mariah had wept until she had no more tears.

Then she had begun planning to get back to the only home she had ever known – the Rocking M.

The Jeep clattered over the cattle guard that kept range cows from wandering out of the Rocking M's huge home pasture. Shrouded by dark memories, Mariah didn't notice the rattling noise the tires made as they hurtled over pipe.

Nor did Cash. He was watching Mariah covertly, accurately reading the signs of her discouragement. No matter how many times he told himself that Mariah was just one more female looking for a free ride from a man, he couldn't help regretting being so blunt about the possibilities of fixing her car. The lost look in her eyes was a silent remonstration for his lack of gentleness. He deserved it, and he knew it.

Just as Cash was on the verge of reaching for Mariah and stroking her hair in comfort, he caught himself. In silent, searing terms he castigated himself for being a fool. A child learned to keep its hands out of fire by reaching out and getting burned in the alluring dance of flames. A man learned to know his own weaknesses by having them used against himself.

Cash had learned that his greatest weakness was his bone-deep belief that a man should protect and cherish those who weren't as strong as himself, especially women and children. The weakest woman could manipulate the strongest man simply by using this protective instinct against him. That was what Linda had done. Repeatedly. After too much pain, Cash had finally realized that the more vulnerable a woman appeared, the greater was her ability to deceive him.

If the pain had gone all the way to the bone, so had the lesson. It had been eight years since Cash had trusted any woman except Carla, his half sister, who was a decade younger than he was and infinitely more vulnerable. From the day of her birth, she had returned his interest and his care with a generous love that was uniquely her own. Carla gave more than she received, yet she would be the first one to deny it. For that, Cash loved and trusted Carla, exempting her from his general distrust of the female of the species.

Wrapped in their separate thoughts, sharing a silence that was neither comfortable nor uneasy, Cash and Mariah drove through the home pasture and up to the ranch buildings. When he parked near the house, she stirred and looked at him.

"Thank you," she said, smiling despite her own weariness. "It was kind of you to go out of your way for a stranger."

Cash looked at Mariah with unfathomable dark eyes, then shrugged. "Sure as hell someone had to clean up the mess you left. Might as well be me. I wasn't doing anything more important than looking at government maps."

Before Mariah could say anything, Cash was out of the Jeep. Silently she followed, digging her keys from her big canvas purse. She unlocked the trunk of her car and was reaching for the carton her stepfather had given her when she sensed Cash's presence at her back.

"Planning on moving in?" he asked.

Mariah followed Cash's glance to the car's tightly packed trunk. Frayed cardboard cartons took up most of the space. A worn duffel crammed as full as a sausage was wedged in next to the scarred suitcase she had bought at a secondhand shop. But it wasn't her cheap luggage that made her feel ashamed, it was Cash's cool assumption that she had come to the Rocking M as a freeloader.

Yet even as Mariah wanted fiercely to deny it, she had to admit there was an uncomfortable core of truth to what Cash implied. She did want to stay on at the Rocking M, but she didn't have enough money to pay for room and board and fix her car, too.

The screen door of the ranch house creaked open and thudded shut, distracting Cash from the sour satisfaction of watching a bright tide of guilt color Mariah's face.

"Talk about the halt leading the lame," said a masculine voice from the front porch. "Are you towing that rattletrap or is it pushing your useless Jeep?"

"That's slander," Cash said, turning toward the porch. He braced his hands on his hips, but there was amusement rather than anger in his expression.

"That's bald truth," the other man retorted. "But not as bald as those sedan's tires. Surprised that heap isn't sitting on its wheel rims. Where in hell did you-" The voice broke off abruptly. "Oh. Hello. I didn't see you behind Cash. I'll bet you belong to that, er, car."

Mariah turned around and looked up and felt as though she had stepped off into space.

She was looking into her own eyes.

"L-Luke?" she asked hoarsely. "Oh, Luke, after all these years is it really you?"

Luke's eyes widened. His pupils dilated with shock. He searched Mariah's face in aching silence, then his arms opened, reaching for her. An instant later she was caught up in a huge bear hug. Laughing, crying, holding on to her brother, Mariah said Luke's name again and again, hardly able to believe that he was as glad to see her as she was to see him. It had been so long since anyone had hugged her. She hadn't realized how long until this instant.

"Fifteen years," Mariah said. "It's been fifteen years. I thought you had forgotten me."

"Not a chance, Muffin," Luke said, holding Mariah tightly. "If I had a dime for every time I've wondered where you were and if you were happy, I'd be a rich man instead of a broke rancher."

Hearing the old nickname brought a fresh spate of tears to Mariah. Wiping her eyes, smiling, she tried to speak but was able only to cry. She clung more tightly to Luke's neck, holding on as she had when she was five and he was twelve and he had comforted her during their parents' terrifying arguments.

"Without you, I don't know what would have happened to me," she whispered.

Luke simply held Mariah tighter, then slowly lowered her back to the ground. Belatedly she realized how big her brother had become. He was every bit as large as Cash. In fact, she decided, looking from one man to the other, they were identical in size.

"We're both six foot three," Luke said, smiling, reading his sister's mind in the look on her face. "We weigh the same, too. Just under two hundred pounds."
