something inside him was shifting, a new creed taking hold. Herbalism, he said, was a spiritual doctrine that separated the wheat from the tares, the faithful from the faithless. Then he used a word I’d never heard before: Illuminati. It sounded exotic, powerful, whatever it was. Grandma, he said, was an unknowing agent of the Illuminati.
God couldn’t abide faithlessness, Dad said. That’s why the most hateful sinners were those who wouldn’t make up their minds, who used herbs and medication both, who came to Mother on Wednesday and saw their doctor on Friday—or, as Dad put it, “Who worship at the altar of God one day and offer a sacrifice to Satan the next.” These people were like the ancient Israelites because they’d been given a true religion but hankered after false idols.
“Doctors and pills,” Dad said, nearly shouting. “That’s their god, and they whore after it.”
Mother was staring at her food. At the word “whore” she stood, threw Dad an angry look, then walked into her room and slammed the door. Mother didn’t always agree with Dad. When Dad wasn’t around, I’d heard her say things that he—or at least this new incarnation of him—would have called sacrilege, things like, “Herbs are supplements. For something serious, you should go to a doctor.”
Dad took no notice of Mother’s empty chair. “Those doctors aren’t trying to save you,” he told Grandma. “They’re trying to kill you.”
When I think of that dinner, the scene comes back to me clearly. I’m sitting at the table. Dad is talking, his voice urgent. Grandma sits across from me, chewing her asparagus again and again in her crooked jaw, the way a goat might, sipping from her ice water, giving no indication that she’s heard a word Dad has said, except for the occasional vexed glare she throws the clock when it tells her it’s still too early for bed. “You’re a knowing participant in the plans of Satan,” Dad says.
This scene played every day, sometimes several times a day, for the rest of the trip. All followed a similar script. Dad, his fervor kindled, would drone for an hour or more, reciting the same lines over and over, fueled by some internal passion that burned long after the rest of us had been lectured into a cold stupor.
Grandma had a memorable way of laughing at the end of these sermons. It was a sort of sigh, a long, drawn-out leaking of breath, that finished with her eyes rolling upward in a lazy imitation of exasperation, as if she wanted to throw her hands in the air but was too tired to complete the gesture. Then she’d smile—not a soothing smile for someone else but a smile for herself, of baffled amusement, a smile that to me always seemed to say, Ain’t nothin’ funnier than real life, I tell you what.

IT WAS A SCORCHING AFTERNOON, so hot you couldn’t walk barefoot on the pavement, when Grandma took me and Richard for a drive through the desert, having wrestled us into seatbelts, which we’d never worn before. We drove until the road began to incline, then kept driving as the asphalt turned to dust beneath our tires, and still we kept going, Grandma weaving higher and higher into the bleached hills, coming to a stop only when the dirt road ended and a hiking trail began. Then we walked. Grandma was winded after a few minutes, so she sat on a flat red stone and pointed to a sandstone rock formation in the distance, formed of crumbling spires, each a little ruin, and told us to hike to it. Once there, we were to hunt for nuggets of black rock.
“They’re called Apache tears,” she said. She reached into her pocket and pulled out a small black stone, dirty and jagged, covered in veins of gray and white like cracked glass. “And this is how they look after they’ve been polished a bit.” From her other pocket she withdrew a second stone, which was inky black and so smooth it felt soft.
Richard identified both as obsidian. “These are volcanic rock,” he said in his best encyclopedic voice. “But this isn’t.” He kicked a washed-out stone and waved at the formation. “This is sediment.” Richard had a talent for scientific trivia. Usually I ignored his lecturing but today I was gripped by it, and by this strange, thirsty terrain. We hiked around the formation for an hour, returning to Grandma with our shirtfronts sagging with stones. Grandma
