“Nope.” Marcy shook her head. “I can’t move past that. He built Capri for Penn and her sisters?”

“He wanted to set things right, but I knew that could never be,” Diana said. “Penn will never be anything but evil.”

“So you granted her immortality and horrific powers,” Gemma said. “That seems reasonable and really fair to every other creature living on the earth.”

“I don’t care if she destroys the entire planet, as long as she’s miserable,” Diana said.

“But you lost your daughter!” Harper shouted, unable to hide her anger and frustration any longer. “You know how badly that hurts! And how many other people will have to lose their daughters because of something you created? I will have to lose my sister, my father his daughter, because of a vendetta that’s thousands of years old? Hasn’t there been enough bloodshed? Haven’t enough people hurt and died for Persephone yet?”

“I understand your pain, but the horrible truth is that it will never be enough. No matter what hell Penn goes through, it will never bring my daughter back. So no, she hasn’t suffered enough.” A harsh acrimony stung Diana’s words. “She will never suffer enough.”

“Why are you so focused on Penn?” Lydia asked. She’d been mostly content to let the others steer the conversation, but this, apparently, had been bothering her. “There were four girls who left Persephone alone that day, four girls you cursed.”

“The other two are dead, and they were little more than collateral damage. Just as you are now.” Diana motioned to Gemma then. “In order for Penn and Thelxiepia to be truly punished, I had to take the others down with them.”

“Thelkispediplipa?” Marcy asked, stumbling over the name. “That’s Thea, right?”

“Thea?” Diana said, then nodded. “Unlike Penn, Thea did actually love. She cared deeply for her sisters, and seeing them suffer was her punishment. In truth, the worst of my wrath was saved for Thea.”

“Why? She’s nowhere near as evil as Penn,” Gemma pointed out.

“That is precisely why,” Diana said. “She knew that what she was doing was wrong. She even cared for Persephone, but not enough to keep her safe. Not enough to deny Penn her pleasures to protect my daughter. If Penn was rotten fruit, Thea was the one who watered the tree.”

“All that it takes for evil to triumph is for good men to do nothing,” Lydia said softly, and Diana nodded again.

“That’s why I sent Bastian to seduce Thea, too. But I told him to favor Penn, so that it would break Thea’s heart worst of all. I was hoping maybe she would stand up to her sister, fight for something she loved, but she never did.”

“She never will,” Gemma whispered.

After all she’d seen Penn do, Thea had done little more than step aside and watch it happen. Even when the sisters she claimed to love were murdered, Thea never acted to help them. She’d done nothing but obey until very recently.

Thea had begun to help Gemma, and that was a tremendous act of betrayal against Penn and showed a change growing within her. By giving Gemma the scroll, Thea had proven that she was willing to die to stop Penn, and yet her only attempts at undermining Penn had involved sneaking around behind her back.

It seemed that while Thea was on Gemma’s side, the only thing she truly feared in life wasn’t death but confronting Penn. She would do nearly whatever it took to help Gemma and break the curse, except for standing up to her sister.

“So it seems,” Diana agreed.

“Not to belabor the point, but Achelous really made our town for the sirens?” Marcy asked. “Then why don’t they spend all their time there? Why don’t they love it if it’s supposed to be some kind of siren paradise?”

“Because they hate their father,” Gemma said.

Marcy shook her head. “Then why did they come back?”

“For me,” Diana said. “They were looking for the muse Thalia, hoping she would lead them to me.”

“She’s going to kill you, you know,” Harper said pointedly, and she was so irritated and enraged, Gemma was afraid she might get up soon and slap Diana. “If we could find you, eventually Penn and Thea will, too. And they’ll kill you. You do understand that.”

“I do. And I’ve made peace with it.” Diana looked out the window again. “Maybe I even welcome death. That’s why I’ve made my home so close to Capri. It’s far enough inland that Penn won’t readily travel here, but close enough that it really won’t make it that hard to find.” She breathed in deeply. “Forever is too long for anyone to live.”

“If she kills you, you won’t even see your revenge exacted,” Gemma said. “If you won’t even be here to watch them suffer, then why not end this? Why not let it go?”

“Or just let my sister go,” Harper interjected. “She’s not like them. She didn’t do anything to you or your daughter. Isn’t there a way that she can break free?”

Diana shook her head. “No. The curse binds them all together. I’ve already told you that I won’t help you break the curse.”

“But that’s only because you want to see Penn suffer.” An idea occurred to Gemma, and she licked her lips. “What if I killed Penn? Then would you tell me how to break it?”

Still staring out the window, Diana said, “If you tried to kill Penn, then you wouldn’t need to break the curse.”
