“I don’t know how,” he shot back, crushing out his cigarette. “I’ll be damned if I’m going to be competing with my kid brother.”

The muttered aside had her narrowing her eyes. “I’m not a trophy, Muldoon.”

“I didn’t mean—” With a shake of his head, he leaned on the desk beside her. “Look, this throws me off course, okay? I figured Nick was out making time with some pretty little teenager whose daddy would want her home by midnight, and now I find out he’s coming on to you. If he wasn’t my brother, I’d go knock him around a little.”

“Typical,” she muttered.

He ignored that and tried to think. “It’s probably normal for him to develop—or think he’s developed—feelings for you. Don’t you think?”

“Maybe.” She tilted her head to slant Zack a look. “I don’t want to hurt him.”

“Me either. You could back off, stay unavailable—the way you’ve tried to be with me.”

“I’ve been busy.” All dignity, she lifted her chin. “And we’re not talking about you. In any case, I considered that, but I’m supposed to be his co-guardian. I can’t do that long-distance. Besides, he talked to me tonight. He really talked, and relaxed, and showed me a little of what’s underneath all that defiance. If I cut him off now, just when he’s beginning to open up and trust me, I don’t know what damage I might do.”

“You can’t string him along, Rachel.”

“I know that.” She wanted to lay her head on Zack’s shoulder, just for a minute. She looked down at her hands instead. “I need to find a way to let him know I want to be his friend—just his friend—without crushing his ego.”

Zack took her hand, and when she didn’t pull it away he twined his fingers in hers. “I’ll talk to him. Calmly,” he added when Rachel frowned at him.

“Actually, I wanted to dump the whole business in your lap, but the more I think about it, the more I’m sure he’d only resent it coming from you. How can you tell him I’m not interested without letting him know we discussed his feelings behind his back?” She shut her eyes. “And I’m not feeling very good about that, either.”

“You had to tell me.”

“Yeah, I think I did, just like I think I’m going to have to figure out what to do.”

He ran his thumb over her knuckles. “We’re in this together, remember?”
