Lily Bennett had a question, and she had been saving it.
She saved it all the way through the hospital checkout, and through the ride home in Sheriff Torres's car, and through the first night in the little apartment over Millie's garage where she and her mom were staying until things got sorted. She saved it through breakfast — scrambled eggs that Millie made herself, with cheese melted the way Lily liked — and she saved it all the way out to the diner's back porch, where Mason was sitting on the steps fixing a loose strap on his saddlebag with a pocketknife and a patience that seemed to have no bottom.
Then she sat down next to him, close enough that her shoulder almost touched his elbow, and she asked it.
"Mr. Mason," she said, "what does the wolf mean?"
Mason set the pocketknife down. He looked at her the way grown-ups hardly ever looked at kids — like the question was worth his whole attention.
"Which wolf?" he said.
"The one on your jacket." Lily pointed. "The gray one. Under the moon."
Mason glanced down at his vest, at the patch sewn over his heart: a gray wolf beneath a silver crescent moon. The thread was old and the colors had faded some, but the wolf still looked like it was moving, mid-stride, head up.
"Well," he said, "wolves look out for each other. That's the whole thing about them. A wolf alone has a hard life. But a pack — a pack takes care of its own. The old ones, the young ones, the ones who are hurt. Nobody gets left behind on the trail. That's the rule."
Lily nodded, like this was exactly the kind of rule the world ought to have.
"So the patch means," Mason went on, "that if you're wearing it, you're saying: you are not alone. Somebody's got your back. No matter what."
Lily was quiet a moment. Then she said, "I drew one."
"You did?"
She scrambled up and ran inside — her sneakers slapping the porch boards — and came back with a folded piece of paper, a little crumpled at the edges from being carried around. She unfolded it carefully and handed it to him.
It was a drawing in crayon. A little house with a crooked chimney. And in front of the house, standing guard, a gray wolf under a silver moon — big and careful, the way a dog stands in front of a yard it loves. The wolf's tail curled around the house like a fence.
Mason looked at it a long time.
"Lily," he said, "this is the best wolf I ever saw."
"I made it for Mom's fridge," Lily said. "But — could it be for you too?"
"It already is," Mason said.
That afternoon, Nadine Brooks came to the diner with her sewing basket.
Nadine was sixty-something and moved like the weather — slow on the outside, unstoppable on the inside. She had a silver braid down her back and a voice like gravel in honey, and she had been mending the riders' vests since before Lily was born. She sat down at the corner table, put on her reading glasses, and opened the basket, which held thread and needles and a whole small army of patches.
"Lily," she said, "come here a minute."
Lily went. Nadine held up a patch — small, no bigger than a cookie, cut from the same gray cloth as the riders' patches. On it, in careful silver thread, was a little wolf beneath a little crescent moon.
"Every rider earns their patch," Nadine said. "But there are other kinds of earning. You walked into a diner full of strangers and asked for help when you needed it. That's the bravest thing I ever saw a person do, and I have seen a lot." She looked at Lily over her glasses. "This one is yours. Honorary member of the Gray Wolf Riders. If you want it."
Lily's eyes went wide. "On my jacket?"
"On your jacket," Nadine said. "Hold still."
Lily held very still while Nadine sewed — small, neat stitches, quick as rain. Mason watched from the doorway, his hands in his pockets, and Claire watched from the counter with her hands pressed together, and Millie pretended to be very busy wiping a table that was already clean.
When it was done, Lily stood up and looked down at her jacket. The little wolf sat over her heart, silver moon and all.
Lily turned to Mason. "Do I have to do anything?" she asked. "Like, is there a job?"
