Katara hesitated, one hand wrapped around the wood of the doorway. She chewed on her bottom lip, curious as she stared into the small library. Zuko was sitting on one of the old stuffed chairs with his legs crossed and a book balanced on his knees, so absorbed in whatever he was reading that he hadn't even noticed her open the door.

Shaking her head, Katara closed the door behind her. "What are you reading?" She sat down in the armchair next to him, resting her chin on her forearms.

Zuko jumped, staring up at her in surprise. "Uh, nothing," he mumbled, good cheek flushing pink. "Just something I found."

Katara leaned over her chair, plucking the book out of Zuko's hands, pushing a finger between the pages to keep his place. She leafed through the book, recognizing some of the names as gods of the Fire Nation – Agni was most the most prominent. Katara was surprised to find that the story Zuko had been reading featured her own goddess, La.

"I didn't know there were any stories about Agni and La," Katara wondered aloud, flipping the page. "Where did you find this?"

Zuko cleared his throat. "It must have belonged to Uncle Iroh. I can't see anybody else being interested in those stories." He rubbed his palms on his thighs, fingers tugging at loose threads that stuck out from his loose pants. "I didn't know there were stories like that either."

Katara handed the book back to Zuko, curling her knees under her chin as she watched him. "Is it a nice story?"

"Uh, yeah. It's about Agni realizing his people needed water to and Tui refusing to give it to him because his people only needed fire. La was less selfish and gave water to Agni, but only if Agni gave fire to her people to warm them during the winter."

Katara smiled. "Good. I thought it might be some story about Agni and La defying nature and falling in love or something." As if La would ever fall in love with the Fire God. "I'm glad it isn't."

Zuko made a soft rasping sound that might have been a chuckle. "I don't think anyone in their right mind would write a story like that. The gods would blast them on the face of the earth."

Katara laughed as Zuko opened the book again, settling back in his chair. "Here's another. It's about how Tui became the Moon Goddess. Do you want me to read it to you? Well, I mean – I know you know the story already, but – well, this one could be a different version."

Katara nodded, folding her head on her arms again. "Go ahead. I'll tell you what's wrong."

The corner of Zuko's lip tipped up in a shy smile, rare for him but something Katara loved to see from the new Fire Lord, and pulled the book closer, leafing through to find the right page. As he started reciting, in his deep, rasping voice, Katara couldn't help but smirk at how wrong the story was.
