were monitoring himâit was a close call.â
âSo letâs bring him back,â I said, rising to my feet.
âItâs not safe for him here. Not while the Consort exists.â
âThen Iâll go to him.â
âAnd join the Free Walkers?â
Becoming a Free Walker meant living in Echoes, hidingfrom the Consort, leaving behind my family and Eliot and the plans weâd made. If I joined the Free Walkers, I wouldnât just be a troublemaker. Iâd be a criminal, and Iâd spend the rest of my life running.
âYou make it sound like itâs all or nothing.â
âThereâs no middle ground here, Del. Either youâre ours, or theirs.â
âWhy donât you tell people about cauterization?â I asked. âThe Consortâs convinced you want to destroy the Key World because you wonât cleave. If you explainââ
âYou think they donât know? The Consort knows all about cauterization, and itâs only made them more desperate to stop us.â Her gaze bored into me. âTell me why the Consort cleaves.â
âTo protect the Key World from Echoes,â I said automatically, a response drilled into me from my earliest days.
âWhy else?â
I thought back to all the textbooks Iâd skimmed. âTo harvest their energy and bolster the Key World.â
âExactly. They want to capture as much of the energy as they can, and they get it at the expense of the Echoes. Cauterization would cut off the supply.â
âThen why cauterize? If we need that energy, why wouldnât we continue cleavings?â
âBecause the Echoes need it more. They need it to live.â
I looked at her blankly. âBut theyâre notââ
âEchoes arenât merely copies of Originals. You know that better than anyone.â
I thought of Simon, of all the versions of him Iâd met, each distinct and vivid and whole. âI know. Theyâre real.â
âTheyâre more than real. Theyâre alive. The Consort knows it, just as they know cleavingâthe great and sacred duty of the Walkersâis murder.â
CHAPTER FOUR
S OME SONGS YOU LOVE FROM the instant you hear them. Six notes in, part of you rises up and says yes . Before the melodyâs complete, before youâve heard the lyrics or the bridge, something within you recognizes it as part of your soul, as if itâs been waiting for you all this time.
Ms. Powellâs words were like the chords to a song Iâd always known but never heard. Still, the logical part of my brain resisted.
âEchoes arenât alive. They donât exist until their world has formed. They canât survive unless theyâre tethered to an Original. When we cleave, they donât even notice theyâre unraveling.â
âWith cauterization, they donât unravel. Once the strings are knotted, the Echoes are as alive as you and me.â
âThat doesnât make sense.â I didnât doubt Simonâs Echoes were real. Iâd watched one of them cleave, and the horror of the moment had stayed with me. But real and alive were different . Alive meant independent. It meant Simonâs Echoes could survive without him.
It meant I hadnât just cleaved Simonâs Echo in the park that day. Iâd killed him.
âWhen we cleave, they unravel. When we cauterize, theylive. Even if their Original dies, a cauterized Echo can maintain their signal and live out a natural lifespan,â Ms. Powell said.
A horrible thought struck. âIs Simon dead? I can hear his Echoes, but if he was in Train World . . .â
âSimonâs alive. We pulled him out of Train World before we cauterized it, I promise you.â
Relief washed over me, but only for an instant. âWait. Are you saying the Consortâs been slaughtering Echoes? For years and years? My parents? Addie? Me?â
Every Echo
