The weight of the moonstone slides the gold ring around my finger as I skim over recipes and drawings outlined in charcoal, until I find what I’m looking for. A simple concoction—a crease folded down the page where the book has been fanned open countless times. The recipe isn’t true witchery. But Grandma used to make it during the cold months of January, to warm chilled bones, to calm a cough, to bring circulation back into numb fingers and toes.

Silently, I descend the stairs to the kitchen.

The ingredients are easy to find. One whole cupboard is lined with glass jars filled with dried herbs and powdered roots and fragrant liquids with descriptions handwritten on the lids. There is even a jar labeled lake water, in case a recipe needed to be made in haste and there was no time to walk the few yards down to the lake itself.

Mom has kept the cupboard stocked, never throwing anything out, even though she doesn’t use the herbs—not like Grandma did.

I pour the few ingredients into the same copper bowl my grandmother once used: ground cloves and powdered cardamom, a dash of fawn lily and burdock root, and a pinch of a reddish-rose tincture labeled bero.

I sift the mixture into a small cotton pouch, then cross the living room to Oliver. His hair is now dry, dark and wavy, and he doesn’t stir when I slide the cotton pouch beneath the blankets beside his bare ribs. His chest rises, the slow measured weight of his lungs expanding. A shudder runs through him and his eyelids flicker, his body tensing briefly—spurred by some dream I can’t see. He reminds me of an animal near death. Fighting it, struggling. I could crawl beneath the blankets and wrap my arms over his chest, I could feel the beat of his heart against my palm, I could wait for the heat to return to his skin before I went back to my own bed.

But he is a boy I don’t know. A boy who smells of the forest now. Who reminds me of the winter trees, tall and lean with bark that is rough and raw and could tear open flesh. No soft edges.

I catch my own breath and turn away. He is a boy I don’t know, I repeat to myself again. He is a boy with his own secrets. A boy unlike all the others—in ways I don’t understand. I can’t pinpoint.

The recipe instructs that the herbs should be kept close to the body while you sleep for three nights in a row, and then the chill will be banished from the bones.

It’s all I can offer him, all I know how to do—I am a Walker without real magic. Without a nightshade. It will have to be enough.
