They had yet to set a new date, and that was making him nervous. Penn wasn’t the type to wait for things. He was afraid she was brewing some other mischief, something that could hurt him or Harper or Gemma even worse.

But right now, he pushed Penn from his mind. He pulled his phone out from his pocket, knowing he needed to focus on his girlfriend. He loved Harper, and if he wanted to be with her, he couldn’t spend all his time worrying about Penn.

So he can’t really tell me anything until I bring him the scroll, Harper texted.

Sorry the teacher couldn’t help you more, Daniel texted back as he walked out of his house.

He locked the door behind him even though he lived out on Bernie’s Island because he didn’t trust Penn or the other sirens not to go in and rummage through his things. Locking the door wouldn’t stop them if they really wanted to get in, but at least there’d be evidence of a break-in, so he’d know they’d been there.

Daniel had made it halfway down the trail to the boathouse when he got another text from Harper: So I was thinking about coming to town for your birthday next week.

Daniel stopped to reply to her since texting and walking had never been his strong suit. He was a few feet away from the boathouse, standing among the cypress and pines, when he typed back to her, You don’t have to do that. We can just celebrate this weekend.

“Ooh, it’s your birthday next week?” Penn asked, her voice mellifluous in his ear.

“Holy crap, Penn.” He wheeled around, shoving his phone in his pocket before she could read any more of the messages, and tried to look like she hadn’t scared him. “You can’t sneak up on a guy like that.”

Penn smiled, apparently proud of having frightened him. Her black hair was dripping wet down her back, and her dress was soaking, so it clung to her flesh. She usually flew over on her visits to the island, but maybe since it was the middle of the afternoon, she thought swimming would be less conspicuous than a giant bird flying in the sky.

“Sorry,” Penn said, without the slightest hint of sincerity.

“How did you do that, anyway? You didn’t make a sound.” He gestured out to Anthemusa Bay behind her, which should’ve made some kind of noise when she climbed out. Not to mention all the pine needles and twigs on the ground that should’ve crunched or cracked under her feet.

She shrugged, still smiling. “It’s an evil-villain trick.”

“Evil villain?” Daniel arched an eyebrow, surprised that she was self-aware enough to realize that’s what she was.

“What?” Penn smirked and started walking to the side, circling him, but he stayed where he was, with his eyes facing forward. “You thought I didn’t know that you’d cast me as the villain in your little soap opera?”

“I’d never really thought of my life as a ‘soap opera.’”

She’d made her way back around and stopped right in front of him, but she was closer this time, nearly touching him. “You didn’t answer my question. It’s your birthday next week?”

“Yeah, on Wednesday.” He nodded. “I’ll be twenty-one.”

A bald cypress had broken in half during the storm last week, so the trunk was leaning down at an angle, almost blocking the trail to the boathouse. Daniel had been meaning to clear it up, but he’d been so busy with everything else that he hadn’t had a chance to.

“You’re still such a baby,” Penn remarked, and she walked back to the fallen tree. She leaned against the rough bark, making it move slightly and the branches groan. “I’m really robbing the cradle with this one.”

“You could try dating a shark,” Daniel suggested. “They live a long time, and they’re the closest thing to your species.”

Penn did not look amused. “Charming.”

“Thanks, and I hate to cut and run like this, but I really have to be going,” he said, and stepped to the side, meaning to make his escape.

She was up in a flash, blocking his path before he even had a chance to react. “Not so fast, Birthday Boy.”

“Listen, Penn, I’m sure you came out here so I could render payment on our little agreement, but I really can’t right now,” he insisted. “We’re having one of the last rehearsals for the play, and I need to be there for last-minute tweaks and touch-ups.”

“I don’t think you’re in a position to tell me what I can and can’t do,” Penn assured him with such cool certainty that it terrified him. “You’re already mine. It’s just a matter of collecting what I’m owed.”

Daniel didn’t even see her move. One second he was standing directly in front of Penn, the next he was on his back. He knew he’d fallen to the ground because he felt twigs cracking under his back and the wind being pushed from his lungs, but, otherwise, he didn’t know how exactly Penn had gotten him there.

He only had a split second to ponder it before Penn was on top of him, straddling him between her legs, and he felt the cold water from her dress seeping in through his jeans.

“Trust me, Daniel.” She smiled down at him as she slid her hands underneath his T-shirt. “You’ll thank me for this later.”

“I seriously doubt that,” he muttered. She leaned forward, pushing up his shirt as she did, and she stared down at his exposed chest and abdomen. He craned his neck up, trying to see what she was getting at. “What are you doing?”
