interrupt.
âYou canât?â Phoebe frowns.
âWhy not?â Troy asks. âWe already know what toâow!â
I shake my head as Troy protects his ribs. I canât tell her. I canât involve her in this. Itâs bad enough Iâm letting Troy inâat least heâs been a part of this world his whole life. Phoebeâs only known about it for a year.
Besides, we might still need them. Surprise twists and all that.
Phoebe crosses the room to stand in front of me. âTell me. I want to help.â
I open my mouth and close it again.
âTell her,â Troy nudges.
Tilting my head back, I stare at the ceiling like Iâm going to find some kind of answer there. Nope, nothing but boring white plaster.
âWeâre friends,â Phoebe says. âYou can trust me.â
âItâs not that,â I blurt. âI trust you, I just . . .â
âDonât want to involve me,â she finishes.
I nod.
âShe didnât want to involve anyone,â Troy adds.
âToo bad,â she says, surprising me. âFriends donât only help each other when itâs safe or convenient. Whateverâs going on, Iâm in.â
I want to argue, to tell her that this is too dangerous. Too risky. Too important. Iâve already been responsible for ruining too many lives. I donât want them to risk their futures, too.
One glance at Troy tells me he agrees with Phoebe.
Two against one. He practically blackmailed me into letting him help. She probably would, too. Doesnât leave me much choice, does it?
âOkay,â I say, walking over to my closet, where the books are safely hidden under a pile of junk. âBut you have to promise not to tell your stepdad.â
She scowls. âDo you even have to ask?â
Of course not. I dig the bigger of the two books out of the hiding spot. I only hesitate a second before walking back across the room. When I hand it to Phoebe, she reads the title and her jaw drops.
âYou said it wasnât possible.â She flips open the book and skims the contents. âYou said it was ridiculously illegal.â
âItâs both,â I reply.
âThen whyââ
She starts to ask the question. Why would I do this? Why would I take such a huge risk?
But then she jerks back, as if it all makes sense.
She glances at Troy, who shrugs and nods.
âYour parents,â she whispers.
I jam my hands in my back pockets. âItâs the only way.â
The gods know Iâve tried everything else. Iâve petitioned Olympus, scoured the legal section of the library, even asked Headmaster Petrolas for advice. The answer was always the same: the decree is irreversible without a unanimous Olympic vote. Hera will never vote in our favor.
If I want to unbanish my parents and bring Griffinâs back to him, I have to try.
âMy only chance to make things right,â I say, âis to go back and stop it from happening in the first place.â
Phoebe stares at me for a long time. Like, an insanely long time. I canât read her thoughtsâI mean, I could use psychospection if I really wanted to, but thatâs rude. Instead, I wait for her to finally speak.
âChanging the past,â she says. âIsnât that dangerous? Wouldnât you risk, like, unmaking yourself?â
âI would already be born,â I argue.
âBut other things,â she insists. âYou could screw up whole time lines that depend on that event happening. My mom used to love this old movie about a time-traveling car andââ
âThere are fail-safes.â Troy points at the book. âAccording to the text, existing time lines are inviolable. Changing something in the past changes it now, but it still happened then.â
âWhat does that even mean?â I demand.
âI know, I had to read it three times to understand,â he says. âBut
