Thea swallowed hard and lowered her eyes. Her expression had become pained, but Gemma couldn’t read it exactly.

“Thea, this doesn’t change anything,” Penn said, trying too hard to sound calm and reassuring.

“This changes everything,” Thea said, then turned back to face Penn. “We’ve believed something for thousands of years, and it’s not true. What else are we wrong about?”

“Maybe it’s a fluke.” Penn shrugged. “But we can figure it out later. I still think we should kill Gemma. She’s more trouble than she’s worth.”

“No, I don’t think so.” Thea shook her head. “We should keep her alive.”

“She’ll just keep running away!” Penn gestured to Alex. “Her being in love is all the more reason that we should kill them!”

“Then we stay,” Thea said.

“What?” Lexi asked, appalled. “We can’t stay here. This town sucks.”

“Just for a while,” Thea said. “Until we figure out what’s going on.”

Penn sighed and seemed to think it over.

“We can’t!” Lexi insisted. “We wouldn’t be able to feed whenever we wanted. We’d have to use discretion so the humans wouldn’t chase us out of town with pitchforks and torches. That means we might have to go, like, weeks without eating.”

“That’s true,” Penn agreed. “But there’s something really weird going on with the boys in this town.”

“What do you mean?” Thea asked.

Penn just shook her head in response. “Fine. We’ll stay. And Gemma can live. For now.”

Lexi groaned loudly, and Gemma tried not to let out a sigh of relief.

“But you will do as I say.” Penn stepped around Thea and walked right up to Gemma. “None of this running off shit or doing what you want. I’ll let you stay here, live with that hideous sister of yours, and run around with this idiot boy. But if you disobey me, if you act out against me or the other sirens, I will not hesitate to kill you all. Do you understand me?”

“I do.” Gemma nodded.

“Do you?” Penn asked. “Because I don’t think you do. We made a similar deal before, and you broke it. In fact, I should be tearing out lover boy’s heart right now just to punish you.”

“Penn, please, I’ll do what you say,” Gemma insisted in a hurried breath. “I’m sorry. I won’t do it again.”

“I know you won’t do it again,” Penn said. “Because I’ve given you more chances than I’ve given anyone else. And you screw up one more time, one more time, and I will destroy everyone you care about. I’ll kill everyone in this entire bullshit town if I have to.”

Gemma swallowed hard. “I understand.”

“Gemma!” Harper shouted as she raced down the embankment toward the docks. “Gemma!”
