damaged limb was splayed behind the soft white pillow of its underbelly. She put her hand out to stroke it, and it flinched, fur trembling.
‘Is it going to die?’
Diego, their father, tethered the horses. He secured the guanaco’s neck in the crook of his arm to stop it biting or twisting, while he felt the fracture and then the pumping strain of its heart. ‘We should do what’s right,’ he said, removing the carved knife from his gaucho belt. Diego’s riding trousers were stained with dirt and sweat, his face obscured by dust. The facón blade glinted in the dwindling afternoon sun.
‘Take Teresita away.’
Behind them, Calida’s twin sat sidesaddle on their shared horse. At ten years old, they should both have been children. But Calida, for all of her two-minute head start, would always be the elder. It was what life had decided: she had been built the sensible one, the one who looked out for and looked after. Occasionally she wished to be as carefree as her sister, to dare a little more, to risk, but it wasn’t in her nature.
‘I don’t want to,’ protested Teresita. ‘I want to see.’
Calida took her sister’s dirt-smeared hand, as native to her as her own. Grudgingly, knowing her father couldn’t be defied, Teresita slid from the saddle.
‘Papa will make it better,’ Calida said. ‘Come on, let’s go for a walk.’
Teresita wore a dust-cracked scowl too determined for her years. She was wilful, stubborn, impossible once she set her mind to something, resolute to have her way no matter the cost: she was their mother’s daughter through and through.
The twins picked their way through sun-charred bramble, Teresita trailing behind like a disgruntled wolf cub, and into a ravine that twinkled with water. Calida crouched to rinse her face. The dust got everywhere; it was the taste of home, grit that caught in their teeth and ears and powder that clung to their eyelashes. All around, the dry green Patagonian steppe rolled into the distance; sharp peaks severed the vista and then flattened into grassy plains, like the whipping surface of a vast and angry sea.
‘What’s Papa doing?’ asked Teresita.
‘Nothing. Forget it.’
But Teresita wouldn’t. She always demanded to know, to find out. She was always asking these dumb questions that Calida didn’t know the answers to.
‘I can hear it screaming. Does it hurt?’
‘No,’ said Calida, putting an arm round her. ‘Come here.’
She drew Teresita close. Her sister’s hair smelled of the horses: the rich, solid scent of the saddlebags and the coarse rope of the reins, the leather stirrups, the tangy metal bit they put between Paco’s teeth and heard him crunch on like an apple core.
The guanaco shrieked a final time. Teresita pushed against her; whether with fear or resistance it was hard to say. Calida had felt her twin’s push from the very beginning: when they were born, a strength driving behind her, indignant at having been left behind. Hurry up, come on, get out, it’s my turn … When she had been old enough to identify it, and recognise in Teresita’s mop of black hair and huge jet eyes the sister she would love until the ends of the earth, Calida sensed that push so often in her life. Teresita’s struggle when she was crying and didn’t want to be comforted; her wishful gaze, reaching beyond the perimeter of the farm and into the frightening unknown; her resentment of gravity when all she longed to do was fly. Calida stayed on the ground, arms out, ready to catch her if she fell.
But there was a pull, too; a force of belonging that could never be changed and never be dimmed. It was blood, a mirror heartbeat, a laugh that echoed her own. At night, when they lay in their bunks, giggling in the dark or making hand shadows on the wall, whispering secrets that didn’t need to be told because they already belonged in each other’s hearts, Calida knew that this connection was a rare and precious gem. Faith. Trust. Devotion. Loyalty. No matter what, the sisters were there for each other.
‘What’s going to happen when we’re grown up?’ said Teresita now.
‘I don’t know. I haven’t thought about it.’
‘Mama says not to do what she did.’
Calida didn’t reply. Instead, she said: ‘We’ll be together, though, won’t we? So it doesn’t matter. We’ll always be together, you and me. Promise?’
Teresita ran a hand across the brittle earth. She blinked against the sun, and gave Calida a smile that warmed her bones. ‘Promise. Can we go back yet?’
Calida went up the ridge to check. Diego was untying the horses. The guanaco was gone and she saw the slash of blood on her papa’s bombachas and dared herself not to look away, to be the big girl Diego always told her she was.
Paco chewed lazily on a tuft of yellow grass.
‘Come on, then,’ said Calida.
Every day the sisters went riding with their father, while Julia stayed at home. It had been that way since time began. Their mother rarely emerged and the girls knew not to make noise in that part of the ranch, especially when Julia was resting.
Calida tried not to feel sad at how, on Julia’s better days, she would invite Teresita into her bedroom; Calida would listen at the door, shut out of their exchange, desperate to hear and be part of the confidence, until she heard her papa’s tread and shame directed her away. Julia spent hours brushing Teresita’s ebony hair and singing her songs, telling her stories of the past and stories of the future, assuring her what a magical woman she was destined to become. Her mama adored Teresita, because Teresita was beautiful. The twins’ division was responsible for this injustice, marking their physical difference: Teresita as exquisite and Calida as average. Calida knew there were greater things in life than beauty, but still it hurt. She wasn’t special, or in any way extraordinary, like her sister. If she were, her mama would love her more.
Once upon a time, when Julia had first been married, she herself had been a magical woman. Calida had seen the evidence, photographs her father had taken when they had worked the land as a couple: Julia against the melting orange sunset, her head turned gently away and her hair in a thick plait down her back. The horse’s tail had been frozen in time, a blur when it had swished away flies. Calida loved those pictures. This was a woman she had never known. She longed to ask her mama about that time, and what was so different now, but she was afraid of making Julia angry.
Julia told Teresita those things, anyway. At least she was telling someone.
Summer 1995 was unbreakingly hot. Sunshine spilled through open doors, the heat bouncing off wood-panelled walls. The twins were in the kitchen, paper pads balanced on their knees. Their home tutor was a harsh-looking woman called Señorita Gonzalez. Gonzalez was thirty-something, which seemed ancient, and the way she wore her hair all scraped back from a high forehead and her glasses on the end of her nose only made her more alarming. She wore heavy black boots whose tops didn’t quite reach the hem of her sludge-coloured skirt, so that a thin strip of leg could be seen in between. In classes, Teresita would giggle at the black hairs they spied lurking there, and Calida had to tell her to shut up before they got told off. Gonzalez was strict, and wasn’t afraid to use their father’s riding switch if the occasion arose.
‘I’m hot,’ said Teresita, kicking the floor in that way she knew drove Señorita Gonzalez mad. Calida’s own legs were stuck to the wooden chair,
