“Indeed, be careful,” Belial sneered, drifting closer to her. There was a stench in the air around him, like old rubbish burning. “Little stupid child, little helpless human. You know where your power comes from now—from Lilith. Not from good as you thought, but from evil. She is off now licking her wounds, but she will return, and she owns you. Anytime you draw a weapon, she will be summoned. You will never escape her.”

Cordelia cried out. She raised Cortana again, knowing there was no use, no point—

Suddenly James was there, throwing an arm around her from behind. He seemed heedless of Cortana as he drew her back against him, whispering in her ear, “ ‘Neither death, nor life, nor angels, nor demons, nor principalities, nor powers, nor things present, nor things to come, shall be able to separate us.’ Do you understand? Keep hold of me, Daisy. Keep hold of me and don’t let go.”

She heard Lucie cry out. Looking down, Cordelia saw that the arm around her had begun to fade at the edges. The tips of James’s fingers turned black—the darkness spread, up his arm, through him. He was becoming a shadow.

But something more was happening. Darkness spread from him and into her at the point of contact between their two bodies. She watched her forearm, where his hand rested, go cloudy and dark. A strange sensation passed through her, a feeling of travel without movement, of transforming into something both less and more than herself.

Was this what it had always been like for James when he tumbled into the shadow realms? For the world had gone dark around her, the trees standing out stark white against a black sky, the paths branching like bones through the skin of a hazy, tenebrous world. The sun glimmered like a coin at the bottom of a murky pool. Lucie was a shadow; Belial a dim shade with gleaming eyes.

The shadows had spread up Cordelia’s arm and down to her wrist, through her hand, passing into Cortana. The blade alone had color. The blade alone shone, golden, in the darkness.

Before Belial could react, Cordelia leaned forward—James’s arm still around her—and plunged the blade into his chest, directly below the wound she’d given him before.

Belial twisted, impaled on her blade as a darker shadow—blood? essence?—spilled from the new wound; head thrown back, he shrieked soundlessly at the sky.

And the sky answered. Briefly, the world seemed to yawn apart—the clouds parted like tearing fabric, and Cordelia saw past them to a vast plain of darkness, starless and infinite. Out in that darkness swirled the great horrors of the voids between worlds, the emptiness where evil grew hungry and intemperate, where the Princes of Hell stalked in all their power, the cold rulers of nothingness.
