Rime

Rime had learned about frost as a young hare.

The first frost she ever saw frightened her — the whole world laced overnight in strange white crystals, and she was sure some cold magic had crept in, or that a silent storm had come, and she huddled in her burrow afraid to look.

Her grandmother, an old hare white for the season, coaxed her out into the sparkling morning. "It's not magic, and no storm came," she said gently. "It's just the air, wringing out its water onto the cold — the same as the summer dew, only frozen." She touched a frosted twig. "On a clear cold night, surfaces get very cold, they chill the air right above them below freezing, and the air's invisible water settles onto them and freezes into these little crystals. Beautiful, harmless, ordinary." She smiled. "You've seen dew on a warm morning. This is the same thing, on a cold one. The world didn't get magicked. It just got cold enough for the dew to come out as ice."

Rime looked at the frost differently after that — not cold magic, but the winter cousin of summer's dew, water from the air frozen onto the cold. And she learned to expect it: clear cold nights, frosty mornings. The frightened, cold-magic feeling turned into a bright, knowing calm. The frost was no mystery. It was just dew, grown on a freezing night.

When she was older, Rime bounded to the WeatherForge academy, where Gale, who ran it, asked, "What is frost, if not frozen rain?"

Rime didn't answer with a speech. She breathed on a cold metal plate, and a faint frost formed. "It's frozen dew," she said. "The air's invisible water settling onto surfaces cooled below freezing — coming out as ice crystals instead of liquid drops. Nothing falls from the sky; the frost grows right there on the cold grass, out of the air, the same way dew does on a warmer night." She tapped the frosted plate. "That's why clear, cold, calm nights bring the heaviest frost — the surfaces cool fastest, chill the air past freezing, and the water crystallizes straight onto them."

Gale's eyes crinkled warmly. "Some think frost is snow, or frozen rain," Gale said.

"It's dew that froze as it formed — grown on the surface, not fallen from the sky," Rime said. Gale smiled. "Then come in," Gale said. "WeatherForge needs someone who knows where the frost comes from."

In her classroom one afternoon, a puzzled young mouse frowned at a frosty window.

"My window has ICE on the inside," the mouse said, "in pretty feathery patterns. But it's not snowing, and the window's not broken. Where's the ice coming from? It's spooky."

"It's coming from the air inside your warm room, freezing onto the cold glass," Rime said gently. "Let me connect it for you. You know how a cold glass of water 'sweats' — the air's water condensing onto it as drops?" The mouse nodded. "Frost on your window is the SAME thing, but the glass is below freezing, so instead of liquid drops, the air's water freezes onto it as those feathery ice patterns." She traced the frost-ferns. "Warm room air holds lots of invisible water; it touches the freezing-cold windowpane; and the water comes out and freezes right onto the glass. It's frozen dew on your window — window-frost."

The mouse looked at the feathery ice. "So it's not snow, and the window's fine. The room's air had water in it, and the cold glass froze that water into these patterns."

"That's the whole craft," Rime said. "Frost — on the grass, the fence, or your window — is always the same: the air's invisible water settling onto a below-freezing surface and turning straight to ice. Not frozen rain, not snow, not magic — just dew, grown cold. Once you know it's frozen dew, frost stops being spooky and starts being one of the loveliest, most ordinary things the cold air makes."
