Harry Potter & Percy Jackson: Dark Waters.

"A gift from My Lady," Zoë said. "We use it while on the Hunt, during bad conditions, or when time is of the essence. In an effort to not become reliant on it, we will pitch our tents normally under normal conditions."

"Whoa," Harry just said. Zoë gave him an amused look before approaching her tent, and making it fold back into its pack-of-gum format, which she put back into her pocket. "Now, I do believe I gave thee a task to perform."

Harry nodded hurriedly and quickly went back to work. "Sorry, Miss Zoë."

She seemed even more amused now. " 'T is always fun to see the reaction to My Lady's folding tents."

Harry didn't react, feeling as if she were teasing him. After he broke the tent down, he put it back up using the quicker technique she had just shown him. It took him a couple of times to get it right – contrary to Artie's technique, this one left him with a collapsed tent on the first few tries before he got it right.

"Good," she said, when he finally managed. "Now, do it again."

Harry simply nodded; he was used to performing a task over and over again for Artie. This was no different, and so he broke it down and did it again. And again. And again. Until Zoë determined that he did it 'right' and had the technique down.

"Good," his new teacher decided. "Repack they pack and we shall return to camp."

"Okay, Miss Zoe," Harry said, doing his best to repack everything as it was supposed to. He felt good about what he learned, but his nerves were hammering about her decision. Would she continue to teach him, or not? He hoped so; she appeared really cool and had taught him a neat new way of packing a tent.

After packing his tent, and finally documenting the changes she made to the straps so he could carry it somewhat comfortably, he followed her back to camp. During the voyage, she kept up a constant commentary on the plants and trees along the way, which forced Harry to scribble notes while on the go.

A couple of times, he nearly ran into a tree, only managing to avert a collision at the last moment.

As they emerged from the tree line, Zoë halted her narration. "Good. Thou needst to learn to keep watch on thy surroundings. Thou never knowest when thou may need it." Harry just nodded, huffing again from both trying to keep up with her long strides, and from trying to keep both an eye on his surroundings and writing notes at the same time. He ignored how her accent came and went, it was unique and he rather liked it. Even if it made her hard to understand sometimes.

They arrived back at the Hunters' camp, and Zoë had Harry stow the backpack where he had gotten it – after adjusting the straps back to their original configuration so they wouldn't bother the next Hunter who used it.

He exited the tent and found his new teacher and his previous teacher locked in discussion.

"Thou art correct, My Lady," Zoë was telling Artie. "He appears quite eager and dedicated."

Artemis, to her credit, didn't seem to be gloating, but looked decidedly smug in Harry's opinion. He approached them, and grinned. "Miss Zoë's awesome," he told Artie.

The Goddess of the Hunt turned from smug to amused. " You liked your lesson, then? Will you continue them?" Harry nodded eagerly. "For as long as Miss Zoë wants," he answered, suddenly feeling his nerves again. He looked plaintively at her.

The Hunter in question sighed. "Very well. We shall continue they lessons whenever there is time."

"Thanks, Miss Zoë!" the boy shouted.

"Thou art welcome," she just answered. "Maintain thy attitude, and there will be no issue." Harry just grinned, before realizing that the sun was setting. He hadn't realized how much time he had spent in the woods with his new teacher, but now that he saw the sun he realized how late it had gotten.

"Oh no, I should head back," he said, slightly urgently. "Before Hestia gets worried. She likes to check up on me."

Artie looked amused again. "I found it best not to upset Aunt Hestia, I agree with you," she told the young boy.

Harry hugged his second favorite goddess. "Thanks for everything, Artie." "You're welcome, harry," she said, breaking the embrace.

Harry turned to Zoë. "Hug?" he asked.

The Huntress eyed him like she wanted to slit his throat. "I think not."

Harry shrugged, grinning, and held out one hand. " Thanks, Miss Zoë."

She shook her head, then clasped his hand. "Thou art welcome."

Harry nodded enthusiastically. "Miss Zoë's awesome! She speaks like before spelling was invented, it's great fun!"

Hestia smothered a laugh, knowing how the Hunter would react to such an admission. She was prickly about the English language, and how often it changed. "So you learned a lot, then?" the goddess asked, changing the subject.

Harry nodded again. "She taught me to put up a tent quicker than Artie's method," he said. "And she taught me a lot of new plants and trees and things. She said she'd keep teaching me as long as I kept working at it."

Harry released the handshake, turned, and walked to the fire. "Doest thou not need transportation?" He heard Zoë ask.

The boy shook his head, waved his hand at the campfire, and thought the special activation phrase Hestia had taught him. He should be careful with it; you never knew who was listening.

The fire turned green. Harry turned around, waved at Artie and Zoë, then spun and stepped through the flames into the temple he now called home.

He emerged from the fireplace, and set out to the kitchen, suddenly realizing that he was extremely hungry.

He hadn't made it more than ten steps, before the fire whooshed behind him. He turned, and raced to catch his all-time favorite goddess in a hug.

"Hi Hestia!"

"Hello Harry," the kind goddess replied, giving him an amused smile. "Did you have a good time with Artie and her lieutenant?" At least, until he asked Hestia for help and it showed where his interests were. Those subjects he liked, like science and history, he was very good at. Those he didn't, like mathematics, he wasn't so good at. So he tried to do his best to keep up on those subjects.

So here he was, doing his sums and subtractions. And multiplications. And divisions. The fireplace in the living area whooshed, and Harry looked up, watching his all-time favorite goddess walk to wards him.

He got up from the table, smiling widely at her. "Hestia!" he said, giving her a big hug.

"I am glad to hear it," Hestia said, her customary smile in place.

Harry leaned in closer, as if divulging a secret. Hestia, curious, leaned in as well. "Miss Zoë's really pretty, too," he admitted. "But don't tell her I said that. She's a Hunter and I'm not supposed to notice." He finished with his finger to his lips.

Hestia smothered another laugh. "It'll be our secret," she promised.

Harry stepped back, and was about to resume his way to the kitchen, when he stopped and looked at her. " You came in really quickly after I came back. Were you watching me?" Hestia just smiled gently. "I would be a poor goddess if I didn't keep an eye on my favorite mortal," she replied. Her smile widened slightly. "Besides, I don't have to watch you when you're coming home through the hearth."

"Because you're the Goddess of the Hearth and you know what happens with one," Harry said, remembering.

Hestia nodded. "Exactly," she smiled.
