“I don’t completely get it. I’ve tried reasoning with her, but…” Thea shook her head. “Penn doesn’t want to admit she was wrong about Liv, but more than that, I think she just can’t have two ‘bad’ sirens.”

“She’s already trying to find a replacement for me,” Gemma filled in what Thea hadn’t said. “She can’t be troubled to find one for Liv on top of that.”

“Pretty much.”

“I get that Penn hates me, and she’s planning to kill me, but objectively, I’m a lot less trouble than Liv.”

“You’re a different kind of trouble than Liv,” Thea said. “You undermine Penn in a different way. Liv may be extreme, but she’s an extreme version of Penn. They have a similar moral compass. So in Penn’s mind, if Liv could just tone her act down, they’d be totally simpatico.”

“And I may not terrorize the village or throw tantrums all the time, but Penn and I will never be on the same page,” Gemma surmised.

Thea slid back on the couch, so she was lying down. “And, secretly, I think she considers you my ally, and that pisses her off.”

“Why?” Gemma asked. “She doesn’t like you either?”

“No, I think Penn likes me about as much as Penn is capable of liking anyone. But she’s never really been close to anyone, not even when we were young. She always resented that I was close with Aggie and Gia.”

“Gia?”

“Ligea. Our other sister. The one before Lexi.”

“Lexi and Penn seemed kinda close for a while.” Gemma had thought that Penn and Lexi were the closest, especially when Gemma first became involved with the sirens, but obviously, they couldn’t have been that tight.

“Well, Penn tore off Lexi’s wing before she murdered her,” Thea said. “They were allies, maybe, but they weren’t close. I don’t think they ever really enjoyed each other’s company.”

“So you’re saying that Penn has never had any friends?” Gemma asked.

“Not really. Well…” Thea seemed to think, and it was a minute before she went on, almost hesitantly. “There was someone, once. Bastian.”

“Bastian?” Gemma asked.

“Well, Orpheus was his given name.”

A few months ago, that name would’ve meant next to nothing to Gemma, but after she’d spent so much time researching Greek mythology, she instantly knew it. He hadn’t exactly been a god, but he’d been an important figure, renowned for his musical abilities and poetry.

“The musical guy?” Gemma asked. “Didn’t he play like a harp or something?”

“A lyre,” Thea corrected her. “You haven’t heard anything until you’ve heard him play. It was said his songs would make the heavens weep, and it wasn’t an exaggeration. The gods were so pleased with his musical abilities, they granted him eternal life.”

“If he was immortal like you guys, did that mean your siren song worked on him?” Gemma asked.

“No, it didn’t. Penn couldn’t manipulate him. And as much as she loves control, she’s always been the most drawn to the people she has no power over.”

“That’s bizarre,” Gemma said, but it did explain Penn’s infatuation with Daniel.

“Usually, I’d say yes, but there was something about Bastian that you couldn’t ignore. He was gorgeous, but it was beyond that. Charismatic, intelligent, funny, and he had these eyes…” Thea stared off wistfully. “They were blue, but not any shade I’ve ever seen in nature.”

“So you were into him?” Gemma asked.

“He was Penn’s lover,” Thea deflected the question.

“But did she actually love him?”

“I’ve thought about it a lot since then, and I can’t honestly tell you. She believed she loved him, and maybe that’s close enough.”

“What happened with Bastian?” Gemma asked. “If he’s immortal, why isn’t she still with him?”

“Like I said, she couldn’t control him. And one night, he was just…” Thea lowered her eyes, and there was a long pause before she finished her sentence. “… gone.”

“I can’t imagine Penn taking that well.”

Thea snorted. “Hardly. This was nearly three hundred years ago now, and she’s mellowed since then. But at the time, Penn went absolutely insane. I know you think she’s bad now, but you have no idea.”

“What do you mean?”

“She was inconsolable, and for Penn, that means she went on a rampage.” Thea pushed herself up, so she was sitting. “The first hundred years after he was gone, it was a bloodbath. Penn killed anything and everything without remorse. In a fit of rage, she murdered our sister Gia.”

“She just murdered your sister Gia? For like no reason?” Gemma asked.

Thea ran her hand through her hair and looked away from Gemma. “She had her reasons, not that they completely made sense to the rest of us.”

“So why didn’t you stop her?”

“The only way I could’ve stopped her would have been to kill her, and I just…” Thea shrugged. “I couldn’t bring myself to do it. She’s my little sister.” Then she shook her head, as if that’s not what she wanted to say at all. “And I felt responsible.”
