Dag went on in growing elation, “That also explains why beguilement’s so blighted erratic. It depends on how open—or not—the Lakewalker feels about farmers—or about that particular farmer, leastways. I’ve been open to Fawn since almost the beginning, so no imbalance has ever built up in her. Hod…not. Till just now. Ha!” He supposed he’d only frighten Hod and Remo if he jumped up and danced around them all whooping like a madman, but he really wanted to.

Remo looked less enthusiastic. “What do you mean, we beguile each other all the time? We don’t!”

“Beguile and un-beguile both. Ground exchange, in balance, not thwarted. I swear it starts with our mother’s milk, and goes on—not a Lakewalker child comes of age without having received dozens of little reinforcements from dozens of kinfolk or friends for this or that ailment or injury. Grown up and out on patrol, or in camp with our tent-kin, we’re always swapping around. We float in a lake of shared ground. I’d not be surprised to find it’s part of why, when a Lakewalker is cut off from others, we feel so odd and unhappy.”

Remo looked wholly interested but only half-convinced. “Dag, are you sure of this?”

“Nearly. You’d best believe I’ll be watching out for it from now on.”

Fawn asked, “Does this mean you really could teach other makers to heal farmers?”

“Spark, if I’m right, any medicine maker who knew this could treat a farmer without beguiling—if only the maker was willing to take in farmer ground.” He hesitated. That might be a bigger if only than it looked at first. Still, medicine making had never been for the squeamish.

Remo said slowly, “But what would happen to that lake of shared ground if a lot of Lakewalkers started taking in farmer ground? What would happen to the maker?”

Dag fell silent. “I don’t know,” he said at last. “I came out here this morning determined to wring some answers to my questions—and we did! — but it seems I’ve just stirred up a pack of bigger questions. I’m not getting ahead, here.”

After a longer pause, Fawn clambered to her feet and motioned them all off the blanket so she could roll it up. The walk back to the Fetch was very subdued. Although at least Hod had stopped sniffling.

In the warmest part of the afternoon, Dag took Fawn down the island to, as they explained to Hawthorn, scout for squirrels. Hawthorn promptly begged to go along, brandishing a slingshot. Remo, bless him, understood the patrol code, and diverted the boy long enough for them to escape.

Finding a warm nook took a little searching, as the wind was freshening and showing signs of veering northwest, with horse-tail clouds spread in gauzy lines turning the light paler. But a low spot in some deadfall, once it was lined with the good supply of blankets they’d packed along, lent both privacy and comfort.

Over the next few delicious hours, Dag discovered that with his growing control of ground projection he could indeed lay reinforcements in select body parts that did not match his own, but, Fawn reported, it did nothing that his ghost hand didn’t already do better. They compared the techniques a couple of times, to be certain, during which Fawn’s solemnly helpful expression kept dissolving into giggles. Dag chortled in, he trusted, a more dignified fashion. Well, maybe not so dignified in that position…He was unable to test Barr’s assertion about making farmer girls suffer desire because he couldn’t force himself to stay closed to Fawn, and anyway, it would have been like pouring milk into milk and looking for a color change. But he hoped this new support around her hidden malice scars would help with the pain of her next monthly, coming up soon.

“A ground reinforcement doesn’t actually heal a person,” he explained as they lay drowsily intertwined, bodies and investigations temporarily exhausted. “It just strengthens a body to heal itself quicker, or to fight infection better. If the damage is too great or the sickness spreads too fast, the maker’s work gets overwhelmed, too.”

Fawn’s lips pursed. She turned her head in the crook of his arm to dot kisses across his skin. “Can the maker get overwhelmed? Give away too much ground to live?”

Dag shook his head. “You’d pass out, first. It’s not like bleeding, that can go on without your will or awareness. Although the exhaustion can lay the maker open to sickness, too, same as anyone else.” He hesitated. “A reinforcement’s not to be confused with a medicine maker’s groundlock, mind you. If a maker’s gone down and in too deep, till matching grounds turns into mixing them, and his patient dies on him, the maker can die, too. The dying ground disrupting the other, see.”

She blinked. “Huh. I wonder if that’s how your ancestors first got the idea for sharing knives?”

Dag rocked back. “Huh! Could be, Spark! Could well be.” Bright farmer girl!

She nodded, brows drawing down. “One way or another, seems like it would be a good idea to keep your strength up.”

“Same as a patrol leader keeping his patrol in good shape, I reckon,” he allowed thoughtfully.

“And the other way around.”

He bent his head and nuzzled her hair. “That, too, Spark.”

The next morning Dag woke to gray skies and extra kisses. Fawn sat up on one elbow, and asked, “Do you know what day this is?”

“I’ve lost track,” he admitted. “Better ask Berry.”

“Guess I’d better.” She grinned and went off to start breakfast.

The clouds thickened but did not deliver rain; the Fetch stayed stuck. After lunch, Whit insisted on dragging Dag off to explore the back side of the island. A wedge of fallen trees and thatch across the channel made a temporary bridge to the mainland, and they picked their way precariously across despite Dag’s assurances that there was nothing over there of note for at least a mile in any direction. When they at last returned to the Fetch, Remo met them on shore with strict instructions from the cook to go catch some fish for dinner, specifically not catfish. This entailed another trip across to the back channel, from which they returned with heavy strings of walleye and three kinds of bass. Bo and Hod took the catch in charge to clean and gut. Then Whit suggested an archery lesson. Remo and Dag set up a target while Whit took the skiff out to the boat for their bows and arrows. In a while Hod and Hawthorn rowed to shore for a turn as well, and by the time they’d worn out everyone, especially the chief instructor, the leaden skies were darkening with early nightfall.

The air of the Fetch’s cabin, when Dag stepped inside, was warm and moist and smelled amazing. He walked into the kitchen area to find it crammed with busy people and festooned with bunches of autumn wildflowers and dried milkweed pods tied with colored yarn. Berry and Fawn were frying up a mountain of fish and potatoes and onions, and Whit and Bo were tapping a new keg of beer set up on a trestle, and where had that come from?

“What are we celebrating?” Dag inquired amiably.

Fawn set aside her pan, walked over, stood on tiptoe, snaked an arm around his neck to pull his face down to her level, and said, “You. Happy birthday, Dag!” And kissed him soundly, to the hoots and clapping of the whole crew congregated. He pulled back, once she released him, with his mouth gaping in astonishment.

“Yes!” Whit whooped. “We got him! We got him good!”

“How did you know this was my birthday?” Dag asked Fawn. It had been upwards of twenty years since he’d paid the least attention to it himself, and he certainly hadn’t mentioned it recently.

“Dag!” said Fawn in fond exasperation. “You gave it to the town clerk when we were married in West Blue! Of course I remembered!”

And Fawn’s was in about six more weeks, as he had learned at the same time and not forgotten—he’d thought they might be in Graymouth by then, and wondered what farmer birthday customs might please her, and been glad that Whit would be there to ask and maybe help keep her from feeling too alone in a strange place. She’ll be nineteen, gods. Dag wasn’t sure whether to feel old, or good, but as Remo pressed him into his seat and Bo thrust a tankard of beer into his hand, he decided on good.
