Theme
A young princess kneels at the edge of a stone well, her golden ball resting on the mossy rim, while a small green frog watches from the water below.

The princess had a golden ball. It was her favorite thing in the whole world. She took it everywhere, even to the pond at the edge of the garden.

One afternoon, she sat on the mossy stones by the water. She tossed the ball up, up, up, and caught it. Up again. Down again. Her hands were quick, but the stones were slick. The ball slipped. It bounced once and rolled into the dark water with a soft plop.

She knelt and peered into the pond. Nothing but black and the little rings widening on the surface. She sat back on her heels and cried. She cried so hard that a frog poked his head out of the water, green and blinking.

“Why are you crying?” he asked.

“My golden ball,” she said. “It fell in. It’s gone forever.”

“I can get it,” said the frog. “But what will you give me?”

“Anything,” she said. “My crown? My pearls?”

“I don’t want those,” he said. “I want to eat from your plate and sleep on your pillow.”

The princess wiped her eyes. “Fine,” she said. “Just get the ball.”

The frog dove. He was gone a long time. Then he came up with the ball in his mouth. He hopped onto the stone and dropped it at her feet. The princess snatched it up and ran for the castle without looking back. Behind her, the frog called out, but she did not slow down.

That evening, the royal family sat down to supper. The king was just lifting his spoon when a knock came at the door. The princess went still. She knew that knock. It was a small, damp sound, like a wet hand on wood.

“See who it is,” said the king.

She opened the door a crack. The frog sat on the step, dripping.

“I’ve come for my supper,” he said.

She slammed the door and hurried back to the table. Her face was red.

“Who was that?” asked the king.

“No one,” she said. “A frog.”

“A frog at the door?” He set down his spoon. “Tell me.”

So she told him about the pond, and the ball, and the promise she had made in a hurry. The king listened with his hands folded.

“You gave your word,” he said.

“But he’s a frog,” she said.

“A promise is a promise,” said the king. “Open the door.”

She opened it. The frog hopped in, leaving little wet marks on the floor. He sat on the kitchen flagstones and looked up at her with round, calm eyes. He had stopped dripping, mostly.

“I’m hungry,” he said. “And I’m not used to waiting.”

She lifted him onto the table, though her fingers flinched. He settled beside her plate. She pushed a spoonful of stew toward him. He ate it neatly, one small bite at a time. She watched him the way you watch a wasp at a picnic.

“Slow down,” said the king from the head of the table. “He’s your guest.”

So she sat and ate her own supper. Every few bites the frog asked for more. By the end, he had eaten half the stew. She was still hungry when the plates were cleared.

“Now I’m tired,” said the frog. “Where do I sleep?”

The princess pointed at the door. “The stable is out there,” she said. “The hay is warm.”

The king set down his cup. “She promised you a pillow,” he said. “That means her pillow.”

Her mouth opened, and nothing came out. She carried the frog upstairs and set him on the far side of her bed. He hopped to the middle, then to her pillow, and settled there with a small, contented sound.

She lay awake a long time. The frog’s breathing was even and quiet, which was somehow worse than if he had snored. When she woke in the morning, he was gone. Only a small damp spot remained, already drying in the sun.

“Good,” she said to the empty room. “Good.”

She told herself she had imagined how heavy the air had felt. She told herself she had imagined the smell of pond water and green things.

The next evening, she watched the door until supper. When no knock came, she almost relaxed. Then, just as the soup was poured, came the small, damp sound again.

“He’s back,” said her father, and he did not look up from his bowl.

She opened the door. The frog sat on the step, dripping as before.

“I’ve come for my supper,” he said.

“You could have stayed away,” she said.

“A promise is a promise,” said the king behind her.

So she let him in. He hopped across the floor and waited by her chair. This time he ate from her plate without asking, and she ate what was left. Her jaw ached from clenching it.

“You’re angry,” said the frog.

“I’m not,” she said.

“You are,” he said. “Your face is doing the thing.”

She did not answer. She carried him up the stairs, set him on her pillow, and turned her back to him. The dark pressed close. The frog said nothing more. In the morning, he was gone again, and the damp spot was smaller.

She found she could not remember the shape of his face. Only the calm, round look of him. Only the way he had said her promise back to her.

The third evening came. The frog was already at the door when she opened it. He hopped past her without a word and waited by her chair. She set her plate on the floor. He climbed onto the rim, eating slowly. She watched the way his throat moved. She watched the way his eyes stayed on her.

“Why do you keep looking at me like that?” she asked.

“Because tonight is the last night,” said the frog.

“The last night of what?”

He didn’t answer. He only finished the last of the bread. Then he sat still, waiting to be carried up. Her arms were tired, but she lifted him anyway. One hand went under his cool, damp belly. The stairs creaked under her feet. In her room, the candle had burned low. The pillow was soft and white. She set him down and lay beside him, facing the wall.

Sleep took a long time coming. The frog breathed in slow, even pulls, like a small bellows. She thought about her promise. She thought about how she had made it in a hurry. She thought about how her father had made her keep it. Outside, the wind pushed at the window, and the dark pressed close.

Then, near midnight, the breathing changed. She felt the pillow shift. Not a hop, but a stretch, like a person turning over. She sat up.

The frog was gone. In his place lay a young man with dark hair and kind, tired eyes. His clothes were too big for him, as if he had been wearing them a long time. He blinked at the candle.

“You broke it,” he said. His voice was low and rusty, like a door opening after years.

“Broke what?” she whispered.

“The spell. It could only be broken if someone kept their word to me. Three nights. You did.” He sat up slowly. “I am a prince, from a kingdom beyond the hills. A witch turned me into a frog. Only a kept promise could turn me back.”

She stared. Her heart was beating fast, but not from fear.

“I didn’t want to keep it,” she said.

“I know,” said the prince. “That’s what made it count.”

In the morning, the king came to the door and found them both awake. He looked at the prince, then at his daughter. He did not seem surprised.

“So,” he said. “The promise held.”

“It held,” said the prince.

“Then you’ll be wanting to go home,” said the king.

They left that day. The prince had a kingdom of his own, he said, and he wanted to see it again. The princess packed a small bag and said goodbye to her father.

“You were hard on me,” she told him.

“A promise is a promise,” said the king. “But you kept it. That’s who you are now.”

They rode in a carriage through the hills. The prince told her about his castle. He told her about his garden. He told her about his servant named Iron Henry. Iron Henry had grieved so long and so hard that he asked a smith to band his heart with iron. He wanted to keep it from breaking.

“He was waiting for me,” said the prince. “He never gave up.”

At the edge of the kingdom, a tall, thin man stood by the road. When he saw the prince, he ran. His face was wet and his hands shook.

“My lord,” he said. “My lord, you’re back.”

“I’m back, Henry,” said the prince.

They drove on, the three of them, through the last of the hills. Somewhere on that road, a small, sharp sound rang out. It was like a band of iron snapping. Then another, and another. The princess looked at Iron Henry. He was smiling, and his hand was pressed to his chest.

“What was that?” she asked.

“Nothing bad,” said Iron Henry. “Just my heart. It’s free now.”

The princess sat back against the seat. She thought of the pond, and the dark water, and the small wet knock at the door. She had kept her word, even when she hated it. That was a thing she could carry. She reached over and took the prince’s hand, and the carriage rolled on toward home.
