Prologue

It was warm. Too warm. The summer heat was getting to her. And despite the fact that Emma Swan was lying on the couch in her mother's air-conditioned apartment, she couldn't shake the feeling that there was something obscenely wrong and it had nothing to do with global warming.

"Emma!" Mary Margaret hissed, as she came running from the bathroom, eyes wide. "Did you not hear your brother crying?"

"What?" Emma stirred suddenly, eyes blinking open in a drowsy motion. "He's crying?"

Mary Margaret sighed in exasperation before rushing over to her bedroom where baby Neal was fussing in his bassinette. Slowly, Emma got to her feet, wondering why her body was coated in sweat and yet she still felt clammy. One second she was boiling; the next, cold as ice. And whilst Mary Margaret was wearing a cardigan to combat the coolness of the air-con, Emma? she felt like she was about to jump out of her skin at any moment.

"Sorry, mom," she apologised as she made her way to the room and poked her head in. Her mother was gently rocking the baby against her shoulder.

"Are you feeling okay, Emma?" she asked in reply, looking at her daughter in concern as she bobbed the child in her arms. "You don't look so good."

"You know what," Emma began slowly, blinking her eyes quickly as her brow furrowed in frustration, "I'm not feeling too hot, maybe I should go home."

"No!" Mary Margaret protested. "If your air conditioner's broken, what good will that do? No, I'll have David make up the spare bed. And I'll call Regina for Henry."

"No, that's okay, he's spending the day with Killian," Emma said absently, her thoughts too muddled to contemplate what her mother would think of that. Instead, she tried to steady herself against the doorway as a rush of dizziness overcame her.

"Emma?" Mary Margaret's frightened voice sounded like it was coming through a thick layer of water. Emma couldn't quite see her. It was moments before there was a blur of white and brown and the floorboards made contact with her head.

"So this is where you and my mom fell through a time portal, right?" Henry looked at the patterned ground in awe. "Cool."

"Aye," Hook frowned, glancing around in curiosity as he wrapped an arm around himself to arm against the sudden chill that had surrounded them upon entering the premises. "It is a bit, isn't it? I must admit, I was getting used to the heat. But to suddenly have this cold snap…perhaps we'd better go, lad."

"Go?" Henry looked up at him before taking a step further into the room. "Come on Hook, where's you sense of adventure."

"I may have lost it when adventure almost cost Emma's existence," Hook answered drily, an odd taste on his tongue. The air was dry and sharp, like the taste of ice. "This feels like magic, Henry."

"So?" he answered with a smile and a knowing look, "Not all magic's bad."

"Aye, lad." Hook was growing frustrated. Something wasn't right here, but he couldn't very well pick the boy up and throw him over his shoulder. "Look, Henry, you…probably shouldn't be touching that."

A silver urn lay open at the centre of the circle and Henry picked it up curiously before comprehension dawned and he asked excitedly, "Did you guys bring this back with you?!"

"Not that I know of," Hook cocked his head. That particular shine of silver looked familiar. "Just leave it, Henry, we should go before something happens."

"Ah, but something has happened."

Killian and Henry spun around just as the metal flew from Henry's hands, landing with a soft 'clink' in the hands of a woman with white-blond hair, her hands sparkling with icy magic.

"Sorry, boys," she answered with a cold smirk, opening the lid. A yelp of surprise and horror escaped Henry and Killian before they were sucked, fully clothed into the small space that existed there.

Elsa smiled in satisfaction and tucked it under her arm, patting it lightly before walking outside into the day that was growing darker by the second. The woman took one look around with her electric blue eyes and smiled.

"I think I'm going to like it here."
