A forest somewhere in Canada

Zoe Nightshade was running through the forest as fast as she can. The forest was full of oak trees, but she avoided crashing into them. Thanks to the moonlight lighting her path.

"Praise Selene." she muttered. Zoe does not need to black out in this tight situation.

She listened for loud human noises. Nothing.

When she first heard the rumors, she had said, "Nonsense." But now … she was the first confirm that the rumors are true. "This is impossible," she had been muttering the whole time.

She tried to picture her mistress and her –

She couldn't. Way too strange.

She kept on running until she reached the oldest and biggest oak tree. This afternoon, she saw her mistress heading here, and she hadn't come back.

Zoe nearly jumped out of her skins when a woman with long auburn hair stepped out from nowhere. "Oh, its you, Zoe."

Panic started building in Zoe's chest. Artemis looked horribly pained, as if a close friend of hers just died. Did something go wrong?

"Is-is e-e-everything a-a-a-alright, m-m-m-my l-lady?" stammered Zoe.

Artemis stared at her lieutenant for one long minute. "Yes," she finally answered, her voice barely a whisper. "They're twins, best of health."

Zoe moaned, "Thank the g-" Artemis put a finger on Zoe's lips. "You won't want the gods to know about this," she said gently.

Zoe nodded. She forgot. They would be in big trouble if the gods knew. At least, her mistress and he will.

"My lady, will thou take them to the Hunters?" Zoe asked.

Artemis shook her head. "Better not. I will send them to an orphanage."

Zoe wondered what would happen if the Hunters know who they are.

"Zoe," Artemis started, "Keep this a secret. Never, by any consequences, tell anyone. Even Hunters. Promise me."

Zoe nodded. She didn't want to tell anyone, either. "I promise."

She had kept her promise. When she died, the secret went with her.

Well, sort of.

Present Day

Johnson Drive No.3, Ottawa

Its not everyday you get to fight an eight feet tall man whom you think as mad.

And that day started as a typical morning.

Jake Parker woke up by falling off his bed, as usual. He groaned and stood. Why does mornings always start like this?

He glanced at his alarm clock beside his bed. It was already time for school, but it hadn't ring. Broken, he decided. Jake walked into his bathroom and looked at his reflection in the mirror. His short, black hair was completely messed up, as usual. Why can't he stop thrashing around while he's sleeping?

Jake put on a shirt over a simple brown t-shirt and faded jeans. He was about to left his bedroom, when he remembered something. The moonstone! He half-ran to his drawer and dug through the junk. His fingers felt something cold. He pulled the object out. It was a strange T-shaped moonstone, it was as big as his hand. His good-luck charm. He brings it everywhere with him. Last time he left it in a toilet, he nearly had a panic attack.

Back then, on his eighth birthday Mrs. Lee, the orphanage's caretaker, gave him this as his birthday present. "It was in your cradle, when I found you and your sister outside the door." she had said. "Perhaps it was from your parents." That encouraged Jake to bring it with him everywhere.

He opened the door and trotted towards the stairs, and bumped into his twin sister.

"Watch it, moron!" Diane Parker yelled.

"You watch it!" Jake yelled back.

"Children!" David, their foster father shouted, "Come down! You're late for school!"

Both grunted and stood, shouldering and cursing each other while climbing down the stairs. Although they were twins, they have nothing alike, except for their bright gray eyes, love for outdoors, hyperactivity, and having dyslexia, which means they can't read or spell properly.

Diane has long auburn hair and two inches shorter than her brother, which she found infuriating.

Both Jake and Diane were extremely good-looking. Jake had quite a number of girlfriends. On the other hand, Diane, often being asked out, though, had no boyfriends. Its like she preferred to be a virgin. Unlike other girls, Diane love to be outdoors, having an adventure, not sitting her butt in her room listening to her iPod and reading magazines. That bore her.

Today, she wore a blue t-shirt (one of her favorites) that said BOYS HAVE FEELINGS TOO and underneath (in bigger letters) I DON'T CARE with black trousers.

When they entered the dining room, their foster mother, Angie, made a big show by kissing their cheeks. Jake looked grateful his friends weren't here.

"HAPPY BIRTHDAY!" Angie shrieked with happiness. "IT'S YOUR FIFTEENTH BIRTHDAY!" Diane thought she was going to be deaf.

Angie brushed her shoulder-length red hair. "Oh, I'm so happy for you two."

I'm happy for myself, too. Diane thought, It's the last day of school. Summer's starting.

Both of them were always nervous whenever they have to go to school, because really weird stuff happened to them. Jake couldn't forget that time when his new girlfriend tried to bite him in the neck. Or when Diane's Math teacher tried to snap her into two.

David grinned at them. He was a successful businessman, middle-aged, like his wife. He had black hair and black eyes, tall and pretty buff. Angie was a businesswoman, working in her husband's company, some inches shorter than David.

"Guess what?" David asked, "After school, we're taking you for a camping trip to the forest!"

Diane smiled. Outdoors. Away from crazy freaks who were going to eat or kill her.

Unfortunately, she was wrong.

Adams High School

David got them to school with his Jaguar and left for work. Jake and Diane entered together. It was a tradition at Adams High for the kids to loiter around the courtyard before the bell rang.

"Yo!" Riley Wood popped out of nowhere. Riley was the Parkers' closest friend (he's the only boy Diane had got close to, but not too close), he had thick, curly, black hair which was always tucked in under a Red Sox baseball cap, and a goatee, although he was only fifteen. Jake found it strange why his friend had not shaved it clean. Goatees look weird in teenagers. Especially for five-feet-tall ones.

Riley had some sort of muscular disease in his legs, so he can't walk properly. But he managed to cope with.

Riley was wearing a t-shirt that said SAVE THE WILD OR BUST. Like the Parkers, he loved nature. He gets pissed off every time someone wipes out trees for building something useless. You wouldn't want to catch him while he's in a bad mood.

He slapped Jake's back. "Happy birthday!" he said, "Oh, and you too, Diane."

She simply nodded.

"Thanks, bro." said Jake.

Riley pointed at a pretty blond girl. "See her? That's Emily Jones. Single. Go check her out."

Jake grinned.

"Perv," Diane muttered.

"Shut up."

When the bell rang, Diane felt like screaming with joy. School's finally out! She and her brother half-ran out of the building, grinning from ear to ear.

Riley met them outside. "Goin' somewhere?"

"Yeah!" Diane exclaimed, "Camping trip in forest."

Was it just her imagination, or did Phillip look horrified for a split second when she said forest?

She frowned. "Something wrong?"

"Nothing," he said. But he wouldn't meet her eyes.

"C'mon," said Jake impatiently, "David's here already."

Sure enough, David's Jaguar was parked in front of the gates.

"Uh, gotta go," Diane told Phillip.

"Wait!" Riley gripped their shoulders. "Bring the moonstones with you, just in case." He paused, then said in a lower voice, "And, Diane, the leather satchel bag."

Diane and Jake stared at him blankly.

BEEP!

"See you next time, bro." Jake said and ran towards the car. Diane followed.

Their foster parents greeted them warmly when they got in. "What's wrong with Riley?" Diane asked Jake. He shrugged. "Dunno. Is it just me or he'd said, 'Bring the moonstones with you, just in case'?"

"Not your imagination." She glanced at her moonstone. Like Jake, she also got one in her cradle. It was a C-shaped, same size as Jake's. On the same day, she got another gift from a stranger. It was a leather satchel bag she was using right now. Back then, Mrs. Lee wanted to throw it away, but Diane said that it might be from her parents, and she insisted to keep it. Mrs. Lee had to give up.

Why the hell did Riley say about bringing a moonstone and a satchel bag?

"Are we there yet?" Jake asked for the twenty-third time.

"No," David replied.

The journey to the forest was taking an eternity. David was probably finding a safe part of the forest. Safe. Jake was itching for an adventure, not some stupid happy-family-camping-trip thing.

"How come it takes so-o-o long to reach there? I'm bored." Diane moaned for the thirty-sixth time.

"It won't be long," Angie assured her.

"Yeah, right," Jake muttered under his breath, "We're in the hundredth mile of nowhere."

The car passed a large man in a dark blue coat wearing a matching blue hat walking on the side of the road.

"Such a coat for a hot day like this," Angie commented.

Jake stared at the man. He was at least seven feet tall. He looked like he was walking, but he was moving at a runner's speed. His senses clicked. Some instinct told him that this guy shouldn't be given a ride. Something was wrong.

"David, can you go faster?" he asked.

"Why?"

"Please?"

"I have to agree," Diane chimed in.

"Children, you have to be patient," Angie said, "We'll reach our camping spot in no time."

He glanced at the man anxiously. Impossible! He was right behind them! "It's not about that, it's about th-"

Before he could finish his sentence, the Jaguar flipped.
