“I don’t know.” Marcy shrugged. “But you guys seem to, and I’ve never known either of you to be totally insane, so I figure there must be some truth to it. Besides that, I always knew something was off with those girls, and they fit the bill as sirens.”

“Oh.” Harper smiled wanly at her. “Well, thanks for the help.”

“No problem.” Marcy smiled back and readjusted her glasses. “My uncle saw the Loch Ness Monster once, too. So I’m a bit more open to things than you.”

Bewildered, Harper shook her head. “Okay.”

“Not that I don’t appreciate the help,” Alex said, as if something had just occurred to him, “but shouldn’t one of you be at the desk in case someone else needs help?”

“There’s a bell up there,” Marcy said. “And this is more important, right?”

Harper normally took her job seriously, but Marcy was right. And Harper had an awful suspicion that if they wanted to help Gemma, they had better do it soon. Or it would be too late.

THREE

Revelations

Despite the fact that the three of them had spent the entire day scouring mythology books, they hadn’t been able to find out much more about how to help Gemma. But when Harper came home from work, she was feeling better than she had since the night Gemma left.

It was reassuring to have Alex and Marcy working with her, even if Marcy wasn’t all that helpful. Harper wasn’t alone, and that made saving Gemma feel more possible.

That feeling of hopefulness evaporated the instant Harper walked through the front door and saw her father.

Brian stood in the middle of the living room. It looked like he’d walked into the room, then forgotten where he was going or why, so he just stopped. He hadn’t shaved that morning, his eyes had bags beneath them, and his skin was ashen.

“Hi, Dad,” Harper said as she closed the front door quietly behind her.

He looked up at her with a ghost of a smile on his lips. “Hi, sweetie.”

“You didn’t end up going to work today?” Harper asked him.

When she’d left for work in the morning he’d still been home, but Harper had been hoping he’d go in. He didn’t have any paid time off left, and their whole family would be in really big trouble if he lost his job. Not only was he the breadwinner of the family, but his health insurance helped keep Harper’s mother in assisted living.

“I thought she might come home,” Brian said, his normally warm voice sounding gravelly from exhaustion and sadness.

“Have you eaten today?” Harper asked, walking past her father toward the kitchen. “I can make you something.”

“I’m not hungry,” Brian said.

“Come on, Dad. I’m making you something.”

Harper went into the kitchen and opened the fridge. She pulled out lunch meat and mayo, and by the time she’d started making him a sandwich, Brian had wandered into the kitchen and sat down at the table.

“Have you heard from her?” he asked.

“No.” She slathered the bread with mayo and refused to look back at him as she spoke. “You know I’d tell you if I had.”

“I just don’t understand why she’d run away,” he said, with a now-familiar frustration taking over. “She had so much she wanted to do. And she was even dating Alex. Why would she leave? Even if she was mad at me.”

“She wasn’t mad at you,” Harper reassured him. She put the sandwich on a plate, then set it in front of her father, still without really looking at him. “You know this wasn’t about you.”

“But it doesn’t make any sense!” Brian insisted. “I called her swimming coach today, and he said that her times have been amazing lately. She worked so hard for that. Why would she blow it to run away with some stupid girls?”

“She’s sixteen, Dad.” Harper went over to the sink to start rinsing off what few dishes had piled up, just so she’d have something to do. “Teenagers are unpredictable.”

“But you guys weren’t,” Brian said, speaking louder to be heard over the running water. “Gemma may be strong-willed, but I’ve always known what I was getting with her. It’s like the last week she’s turned into something else.”

Harper accidentally dropped a plate, and it clattered loudly in the sink.

“And the timing couldn’t be worse,” Brian went on. “There’s that killer on the loose going after teenagers.” He took a labored breath. “Something’s happened to her, Harper.”

“Those were all boys,” Harper said, trying to cut off his train of thought. “And I saw Gemma leave. She told me she was running away. She’s fine.”

“She’s not fine!” Brian shouted.

Harper leaned against the sink and closed her eyes. For a moment all she could do was breathe in deep to keep from freaking out. Her hands were trembling, and she wanted to cry. She had to convince her father that everything was all right, when in reality she had no idea if Gemma was okay or if they’d ever see her again.

“I went to the police today,” Brian said, and his tone had leveled out again.

“Did you?” Harper asked cautiously. “What did they say?”

“They’re looking for her,” Brian said. “They don’t prioritize runaway teens, and with everything that’s been going on lately, they’re going to do what they can.”
