Annie and the girls visited once a year. They were infatuated with Paris. They had dreams of long days filled with creamy light and meals that lasted long into the hazy blur of evening. They loved French ice cream and the glasses of blue-white milk. They studied beautiful women and tried to imitate the way they walked, the way they tied their scarves so prettily. They always traveled to France for spring vacation. The chestnut tree in the courtyard was in bloom then, with its scented white flowers.

The Plaza was probably the second-best place in the world. Annie went to the girls’ room to find her daughters clustered around the window, gazing at the horse-drawn carriages down below. From a certain point of view the sisters looked like women, tall and beautiful and poised, but they were still children in many ways, the younger girls especially. Meg said that when she got married she wanted to ride in one of those carriages. She would wear a white dress and carry a hundred roses. The girls’ secret world was called Arnelle. Arnish for rose was minta. It was the single word Annie understood. Alana me sora minta, Meg was saying. Roses wherever you looked.

“How can you think about that now?” Elv gestured out the window. She was easily outraged and hated mistreatment of any sort. “Those carriage horses are malnourished,” she informed her sister.

Elv had always been an animal fanatic. Years ago she’d found a rabbit, mortally wounded by a lawn mower’s blades, left to bleed to death in the velvety grass of the Weinsteins’ lawn. She’d tried her best to nurse it to health, but in the end the rabbit had died in a shoebox, covered up with a doll’s blanket. Afterward she and Meg and Claire had held a funeral, burying the shoebox beneath the back porch, but Elv had been inconsolable. If we don’t take care of the creatures who have no voice, she’d whispered to her sisters, then who will? She tried to do exactly that. She left out seeds for the mourning doves, opened cans of tuna fish for stray cats, set out packets of sugar for the garden moths. She had begged for a dog, but her mother had neither the time nor the patience for a pet. Annie wasn’t about to disrupt their home life. She had no desire to add another personality to the mix, not even that of a terrier or a spaniel.

ELV WAS WEARING the darkest of the dresses, a deep sapphire, the one her sisters coveted. They wanted to be everything she was and traipsed after her faithfully. The younger girls were rapt as she ranted on about the carriage horses. “They’re made to ride around without food or water all day long. They’re worked until they’re nothing but skin and bones.”

“Skin and bones” was a favorite phrase of Elv’s. It got to the brutal point. The secret universe she had created was a faery realm where women had wings and it was possible to read thoughts. Arnelle was everything the human world was not. Speech was unnecessary, treachery out of the question. It was a world where no one could take you by surprise or tell you a mouthful of lies. You could see someone’s heart through his chest and know if he was a goblin, a mortal, or a true hero. You could divine a word’s essence by a halo of color—red was false, white was true, yellow was the foulest of lies. There were no ropes to tie you, no iron bars, no stale bread, no one to shut and lock the door.

Elv had begun to whisper Arnelle stories to her sisters during the bad summer when she was eleven. It was hot that August; the grass had turned brown. In other years summer had been Elv’s favorite season—no school, long days, the bay only a bicycle ride away from their house on Nightingale Lane. But that summer all she’d wanted was to lock herself away with her sisters. They hid in their mother’s garden, beneath the trailing pea vines. The tomato plants were veiled by a glinting canopy of bottle-green leaves. The younger girls were eight and ten. They didn’t know there were demons on earth, and Elv didn’t have the heart to tell them. She brushed the leaves out of her sisters’ hair. She would never let anyone hurt them. The worst had already happened, and she was still alive. She couldn’t even say the words for what had happened, not even to Claire, who’d been with her that day, who’d managed to get away because Elv had implored her to run.

When she first started to tell her sisters stories, she asked for them to close their eyes and pretend they were in the otherworld. It was easy, she said. Just let go of this world. They’d been stolen by mortals, she whispered, given a false family. They’d been stripped of their magic by the charms humans used against faeries: bread, metal, rope. The younger girls didn’t complain when their clothes became dusted with dark earth as they lay in the garden, although Meg, always so tidy, stood in the shower afterward and soaped herself clean. In the real world, Elv confided, there were pins, spindles, beasts, fur, claws. It was a fairy tale in reverse. The good and the kind lived in the otherworld, down twisted lanes, in the woods where trout lilies grew. True evil could be found walking down Nightingale Lane. That’s where it happened.

They were coming home from the bay. Meg had been sick, so she’d stayed home. It was just the two of them. When the man in the car told Claire to get in the backseat, she did. She recognized him from school. He was one of the teachers. She was wearing her bathing suit. It was about to rain and she thought he was doing them a favor. But he started driving away before her sister got into the car. Elv ran alongside and banged on the car door, yelling for him to let her sister out. He stopped long enough to grab her and drag her inside, too. He stepped on the gas, still holding on to Elv. “Reunina lee,” Elv said. It was the first time she spoke Arnish. The words came to her as if by magic. By magic, Claire understood. I came to rescue you.
