as a hub of science, and yet it had its share of high-tech businesses and innovative labs. My old mate Amalie Sutter, the entomologist, headed one of them. I’d met Amalie years earlier, when she was a postdoc, living about as far as you could get from gilded rococo cafés. I came across her on the side of a mountain in remote northern Queensland. She lived in an upended, corrugated-iron water tank. I was backpacking at the time. I dropped out of my expensive, elitist girl’s school at sixteen, which was the first possible moment I could get free of it. I’d tried to get them to expel me earlier, but they were too scared of Mum to go for it, no matter what outrages against decorum I managed to devise. I walked out of our palatial home and joined that shifting band—the healthy Scandinavian kids on working holidays, the surfie dropouts, and the gaunt druggies—drifting north to Byron Bay and then on up the coast, past Cairns, past Cooktown, until the road ran out.
I’d traveled almost two thousand clicks to get away from my mother, and I ended up finding someone who was, in some ways, exactly like her. Or like she might have been in a parallel universe. Amalie was my mother stripped of social pretensions and material ambition. But she was just as driven by what she did, which was to study how a certain species of butterfly relied on ants to keep its caterpillars safe from predators. She let me stay in her water tank and taught me all about compostable toilets and solar showers. Even though I didn’t realize it at the time, I now think those weeks on the mountain, watching the way she looked at the world with this close, passionate attention, the way she busted her butt just for the chance to find out something new about how the world worked, were what turned me around and headed me back to Sydney, to start my real life.
Years later, when I came to Vienna and apprenticed myself to Werner Heinrich, I ran into her again. Werner had asked me to investigate the DNA of a book louse he’d extracted from a binding, and someone said the DNA lab over at the Naturhistorisches Museum was the best in the city. At the time I thought that seemed odd. The museum was a fantastic antique of a place, full of moth-eaten stuffed animals and nineteenth-century gentlemen’s rock collections. I loved to wander around in there because you never knew what you’d find. It was like a cabinet of curiosities. There was a rumor, though I’d never confirmed it, that they even had the severed head of the Turkish vizier who’d lost the seige of Vienna in 1623. Supposedly, they kept him in the basement.
But Amalie Sutter’s lab was a state-of-the-art facility for the research of evolutionary biology. I remembered the rather bizarre directions to her office: take the elevator to the third floor, follow the skeleton of the diplodocus, and when you reach the jawbone, her door is on the left. An assistant told me she was in the collections room and walked me down the corridor. I opened the door to a pungent blast of mothball odor. There was Amalie, pretty much as I’d left her, poring over a drawer full of silvery blue shimmer.
She was pleased to see me, but even more pleased to see my specimen. “I thought you were bringing me another book louse.” Last time, she’d had to grind it up to extract the DNA, amplify it, and then wait days to do an analysis. “But this,” she said, holding the envelope carefully. “This, if I’m not much mistaken, is going to be a lot easier. I think what you’ve got here is an old friend of mine.”
“A moth?”
“No, not a moth.”
“It can’t be part of a butterfly?” Bits of butterfly don’t generally wind up in books. Moths do, because they come indoors, where books are kept. But butterflies are outdoor creatures.
“I think it might be.” She stood and closed the collection cabinet. We walked back to her office, where she scanned the floor-to-ceiling bookshelves, then hauled down a huge tome on wing veination. She pushed open a tall door that had a life-size picture of her as a graduate student, in the Malaysian rain forest, brandishing a four-meter butterfly net. It was remarkable how little she’d aged since then. I think her absolute enthusiasm for her work acted on her like some kind of preservative. On the other side of the door was a gleaming lab, with postdocs wielding pipettes and peering at DNA graphs on computer monitors. She gently lifted my little bit of wing onto a slide and placed it under a powerful microscope.
“Hello, lovely,” she said. “It is you.” She looked up and beamed at me. She hadn’t even glanced at the veination diagrams. “Parnassius mnemosyne leonhardiana. Common throughout Europe.”
Damn. My heart sank, and my face must have shown it. No new information there. Amalie’s smile widened. “Not much help?” She beckoned me to follow her back down the corridor to the room filled with collection cabinets. She stopped in front of one and opened the tall metal door with a clang. She slid out a wooden drawer. Rows of Parnassius butterflies hovered in their perpetual stasis, afloat forever above their carefully lettered names.
The butterflies were lovely in a subtle, muted way. They had creamy white forewings, splashed with black dots. The rear wings were almost translucent, like lead glass, divided into panes by the distinct tracery of black veins. “Not the flashiest butterfly in the world by any means,” said Amalie. “But collectors love them. Perhaps because you have to climb a mountain to get one.” She closed the drawer and turned to me. “Common throughout Europe, yes. But confined to high alpine systems, generally around two thousand meters. The caterpillars of the Parnassius feed only on an alpine variety of larkspur that grows in steep, stony environments. Your manuscript, Hanna, dear. Has it been on a trip to the Alps?”

Here lies the grave. Stay, for a while, when the forest listens.
Take off your caps! Here rests the flower of a people that knows how to die.

THE WIND BLEW ACROSS the Miljacka River, hard as a slap. Lola’s thin coat was no protection. She ran across the narrow bridge, her hands thrust deep in her pockets. On the other side of the river, a set of rough-hewn stone stairs rose abruptly, leading to a warren of narrow lanes lined with shabby apartment buildings. Lola took the stairs two at a time and turned in to the second alleyway, sheltered at last from the bitter gusts.
It was not yet midnight, so the outer door to her building hadn’t been locked. Inside, it was not much warmer than on the street. She steadied herself and took a moment to catch her breath. A heavy smell of boiled cabbage and fresh cat piss hung over the foyer. Lola crept up the stairs and gently turned the latch on her family’s apartment. Although her right hand reached up instinctively to touch the mezuzah on the doorjamb before she slipped inside, Lola could not have said why. She took off her coat, unlaced her boots, and carried them as she tiptoed past the sleeping forms of her mother and father. The apartment was one room, with a dividing curtain the only privacy.
Her little sister was just a bulge beneath the quilt. Lola lifted the coverlet and slid in beside her. Dora was curled up like a small animal, radiating welcome heat. Lola reached for the warmth of her sister’s back. The child protested in her sleep, uttering a tiny cry and pulling away. She tucked her icy hands into her own armpits. Despite the cold, her face was still flushed, her brow still damp from the dancing, and if her father woke, he might notice that.
Lola loved the dancing. That was what had lured her to the Young Guardians meetings. She liked the hiking, too; the long, hard walks in the mountains to a hanging lake or the ruins of an ancient fortress. The rest of it, she didn’t care much for. The endless discussions of politics bored her. And the Hebrew—she didn’t even enjoy reading in her own language, much less struggling to decode the strange black squiggles that Mordechai was always trying to get her to remember.
She thought about his arm across her shoulder in the circle. She could still feel the pleasant weight of it, muscular from farm labor. When he’d rolled up his sleeves, his forearm had been brown and hard as a hazelnut. Even though she didn’t know the steps, it was easy to follow the dance with him beside her, smiling encouragement. A Sarajevan—even a poor one like Lola—would never give a second glance to
