Which was how Pasha ended up pacing alone in the palace library, working out the morning’s events on his own. “There was lightning, a ring of fallen trees on fire. . . .”

Someone rapped on the open door. Yuliana peered inside the library. “Are you talking to yourself again?”

“Oh. Yuliana. I didn’t hear you come in.” Pasha ran his fingers through his hair, disheveling it even more than fleeing the forest had. It stuck up in dark-blond tufts, like peaks of torched meringue from one of their father’s many banquets.

“You’re muttering to yourself again.” She tapped her sharp fingernails on the door frame. Yuliana was two years younger than Pasha, but most of the time, she seemed to think herself twice his age. “The servants could hear. You don’t want them thinking the tsesarevich is a madman.”

Pasha sighed. “I think they’re rather accustomed to my mannerisms by now. If they don’t already think me mad, they will not think it because of today.”

Yuliana tilted her head. “Suit yourself. But at the very least close the door.” She dipped in a perfunctory curtsy on her way out of the library, then reached for the heavy wooden door and shut it fast behind her. It plowed into the frame with a decisive thump.

Pasha shook his head as soon as she was gone. Sometimes, he wondered how the tsar could be his father, although it was obvious the tsar was Yuliana’s. His sister and father were cast from the same steely resolve. And recently, Yuliana had even seemed the sterner of the two.

But back to the girl. Pasha began to pace the well-worn groove of the carpet again. “She rose as if the fire were nothing . . . no, as if she were part of the fire.” He tugged on his hair again. The girl’s appearance both unnerved and intrigued him. Had she already been there in the woods when the fire began? Or had she come out of the lightning, the cause of the very fire from which Pasha had sought to rescue her?

As quickly as he had begun, Pasha ceased his pacing and crossed the library to a towering bookshelf. The entire room was lined, floor to cathedral ceiling, with books—from old Church documents sealed in airtight cases to new treatises on politics and military strategy. What Pasha was looking for, though, was information on the occult. There would be no books on the subject in the Imperial Public Library, for the Church had ordered any materials on magic destroyed centuries ago. But the palace’s private library was a different matter; if magic did, indeed, exist, and if there were books written about it, they would be here.

As Pasha climbed the ladder to the upper reaches of the wall, a giddiness fluttered within him. Perhaps investigating the girl and her magic was one thing he could do better than Nikolai, who excelled at pretty much everything else, from dancing to sharpshooting to understanding the intricacies of bridge building. Not that Pasha was jealous; he didn’t begrudge Nikolai his talents at all, and in actuality admired him. But he could not help feeling the thrill of a little healthy competition, and Nikolai had seemed frightened of the girl, whereas Pasha had felt nothing but wonderment. Pasha grinned as he perused the highest shelves.

There were dusty spines of poetry from the last century, and novels from abroad in French, English, and German. How had he not seen these before? Out of habit, he reached for several. But he stopped short of pulling them out. This was not the time to lose himself in fiction and the study of foreign literature.

He pushed the ladder sideways, for it had wheels connected to a track on the top and bottom, until he found a row of books on Roman and Greek mythology, followed four shelves below by European fairy tales, and then on the fifth by Russian folklore. The last book on the fifth shelf was a thick leather volume titled Russian Mystics and the Tsars.

“Et voilà,” Pasha said to himself. He pulled the book from its place between Vodyanoi, the Catfish King and The Death of Koschei the Immortal, unleashing a flurry of dust possibly dating from earlier than the previous tsar. He waved the dust away and slid down the sides of the ladder, not bothering with the rungs. His feet landed on the carpet with a solid thump.

Pasha opened the book and sank into his favorite armchair at the same time, his movements easy and graceful, a subconscious compilation of all his experiences growing up in the imperial household, from participating in formal court functions to learning to fence, from watching ballet to being reprimanded when his own posture faltered.

He flipped to the table of contents. The page was yellow and crackled with age.

Chapter 1. Mysticism in Ancient Russia

Chapter 2. Mystics, Enchanters, and Faith Healers

Chapter 3. Extinction of Nymphs and Faeries

Chapter 4. Power, the Wellspring, and the Crown’s Game

He stopped skimming when he saw the subject of chapter 15, the last one in the book: “Mysticism in Modern Times.”

Pasha smiled so broadly, it was as if he’d discovered the secret to eternal life. This was the sort of book one ought to read in pieces, to properly appreciate and savor each bit. And yet he wanted to devour it whole. Messily and all at once.

But he didn’t, because he was the tsesarevich, and crown princes had better manners than that, even when it came to tomes that promised to unveil an entire new world inside. I should, however, at least have the luxury of reading out of order, he thought.

And he thumbed his way to the last chapter, for although this book had been written ages ago, he figured this was the best place to try to understand the girl—what she did and what she was. Pasha hooked a leather ottoman with his foot and dragged it closer, then settled deep into his armchair for a long afternoon of reading.

But he did not admit to himself, either aloud or even quietly in his own head, that he was interested in the girl for more than just her magic.

CHAPTER TEN

They could be coming for me right now, Vika thought as she cast shields around the cottage. Father had warned her not to be seen using magic, and now she’d been caught, and those boys could be summoning a mob to burn her at the stake. She fortified the windows a third time, especially the ones in Sergei’s bedroom. He didn’t deserve to die for her indiscretion. He didn’t deserve to die at all.

Where was he?

She ran outside again, for it was possible that he’d arrived while she was inside and been unable to get in, given how tightly she’d protected their home. She saw him emerge from the forest just as she crossed the threshold of the cottage.
