Delilah Bard — always a thief, recently a magician, and one day, hopefully, a pirate — was running as fast as she could.

Hold on, Kell, she thought as she sprinted through the streets of Red London, still clutching the shard of stone that had once been part of Astrid Dane's mouth. A token stolen in another life, when magic and the idea of multiple worlds were new to her. When she had only just discovered that people could be possessed, or bound like rope, or turned to stone.

Fireworks thundered in the distance, met by cheers and chants and music, all the sounds of a city celebrating the end of the Essen Tasch, the tournament of magic. A city oblivious to the horror happening at its heart. And back at the palace, the prince of Arnes — Rhy — was dying, which meant that somewhere, a world away, so was Kell.

Kell. The name rang through her with all the force of an order, a plea.

Lila reached the road she was looking for and staggered to a stop, knife already out, blade pressing to the flesh of her hand. Her heart pounded as she turned her back on the chaos and pressed her bleeding palm — and the stone still curled within it — to the nearest wall.

Twice before Lila had made this journey, but always as a passenger.

Always using Kell's magic.

Never her own.

And never alone.

But there was no time to think, no time to be afraid, and certainly no time to wait.

Chest heaving and pulse high, Lila swallowed and said the words, as boldly as she could. Words that belonged only on the lips of a blood magician. An Antari. Like Holland. Like Kell.

"As Travars."

The magic sang up her arm, and through her chest, and then the city lurched around her, gravity twisting as the world gave way.

Lila thought it would be easy or, at least, simple.

Something you either survived, or did not.

She was wrong.

A world away, Holland was drowning.

He fought to the surface of his own mind, only to be forced back down into the dark water by a will as strong as iron. He fought, and clawed, and gasped for air, strength leaching out with every violent thrash, every desperate struggle. It was worse than dying, because dying gave way to death, and this did not.

There was no light. No air. No strength. It had all been taken, severed, leaving only darkness and, somewhere beyond the crush, a voice shouting his name.

Kell's voice —

Too far away.

Holland's grip faltered, slipped, and he was sinking again.

All he had ever wanted was to bring the magic back — to see his world spared from its slow, inexorable death — a death caused first by the fear of another London, and then by the fear of his own.

All Holland wanted was to see his world restored.

Revived.

He knew the legends — the dreams — of a magician powerful enough to do it. Strong enough to breathe air back into its starved lungs, to quicken its dying heart.

For as long as Holland could remember, that was all he'd wanted.

And for as long as Holland could remember, he had wanted the magician to be him.

Even before the darkness bloomed across his eye, branding him with the mark of power, he'd wanted it to be him. He'd stood on the banks of the Sijlt as a child, skating stones across the frozen surface, imagining that he would be the one to crack the ice. Stood in the Silver Wood as a grown man, praying for the strength to protect his home. He'd never wanted to be king, though in the stories the magician always was. He didn't want to rule the world. He only wanted to save it.

Athos Dane had called this arrogance, that first night, when Holland was dragged, bleeding and half conscious, into the new king's chambers. Arrogance and pride, he'd chided, as he carved his curse into Holland's skin.

Things to be broken.

And Athos had. He'd broken Holland one bone, one day, one order at a time. Until all Holland wanted, more than the ability to save his world, more than the strength to bring the magic back, more than anything, was for it to end.

It was cowardice, he knew, but cowardice came so much easier than hope.

And in that moment by the bridge, when Holland lowered his guard and let the spoiled princeling Kell drive the metal bar through his chest, the first thing he felt — the first and last and only thing he felt — was relief.

That it was finally over.

Only it wasn't.

It is a hard thing, to kill an Antari.

When Holland woke, lying in a dead garden, in a dead city, in a dead world, the first thing he felt then was pain. The second thing was freedom. Athos Dane's hold was gone, and Holland was alive — broken, but alive.

And stranded.

Trapped in a wounded body in a world with no door at the mercy of another king. But this time, he had a choice.

A chance to set things right.

He'd stood, half dead, before the onyx throne, and spoken to the king carved in stone, and traded freedom for a chance to save his London, to see it bloom again. Holland made the deal, paid with his own body and soul. And with the shadow king's power, he had finally brought the magic back, seen his world bloom into color, his people's hope revived, his city restored.

He'd done everything he could, given up everything he had, to keep it safe.

But it still was not enough.

Not for the shadow king, who always wanted more, who grew stronger every day and craved chaos, magic in its truest form, power without control.

Holland was losing hold of the monster in his skin.

And so he'd done the only thing he could.

He'd offered Osaron another vessel.

"Very well ..." said the king, the demon, the god. "But if they cannot be persuaded, I will keep your body as my own."

And Holland agreed — how could he not?

Anything for London.

And Kell — spoiled, childish, headstrong Kell, broken and powerless and snared by that damned collar — had still refused.

Of course he had refused.

Of course —

The shadow king had smiled then, with Holland's own mouth, and he had fought, with everything he could summon, but a deal was a deal and the deal was done and he felt Osaron surge up — that single, violent motion — and Holland was shoved down, into the dark depths of his own mind, forced under by the current of the shadow king's will.

Helpless, trapped within a body, within a deal, unable to do anything but watch, and feel, and drown.

"Holland!"

Kell's voice cracked as he strained his broken body against the frame, the way Holland had once, when Athos Dane first bound him. Broke him. The cage leached away most of Kell's power; the collar around his throat cut off the...
