Prologue

Year: 2030

When Melinda had been asked at school what she wanted to be when she's older, she might've said; 'doctor' or 'teacher' or possibly 'witch' if she'd been young enough to get away with it. Running down a deserted street, in a post-Apocalyptic world, trying to fend off fire-throwing demons was NOT the first thing that would've come to mind.

"What the hell are those things?" Adam yelled, running a long side her, veering off as a car was hit with a jet of fire and exploded up into the air.

"Mercury demons!" Melinda replied, panting and dodging another exploding car. Adam rolled his eyes and charged at Melinda, grabbing her by her jacket and throwing both of them into an empty building, each scrambling to either side of the opening as another burst of fire flared into the room for a second.

"Whatever it is, the bitch has serious firepower." Adam groaned, coughing slightly.

"It's not fire, it's heat; thermal blasts." Melinda informed him, matter-of-factly. Adam glared at her - looking uncannily like his brother, Dean.

"Whatever Mel, how do we kill it?" he demanded. Melinda shrugged.

"Could try blowing it up." she suggested.

"No damn way!" Adam protested, but Melinda had already broke cover and positioned herself into the doorway. "Melinda!" Adam yelled as Melinda flicked her hands - only to be thrown backwards by the force of the blast. Adam darted out as soon as the blast had dissipated and ran to Melinda's side. "You okay?" he asked, shaking her shoulder roughly.

"OW!" Melinda protested, sitting up and coughing, the ends of her hair singed slightly. "That's hot." Adam didn't know whether to hug her or yell. Luckily he was saved making a choice by Chris orbing in.

"Need help?" he asked, an eyebrow raised.

"We're fine!" Melinda told him, struggling to stand but only falling back onto the floor. Adam and Chris exchanged looks.

"You look it." Chris noted. Melinda narrowed her eyes.

"Just tell us how to kill the thing." she ground out.

"You can't. Only the Power of Three can kill a Mercury Demon." Chris told her, indifferently.

"Great. Where's Wyatt when you need him?" Adam muttered.

"Well, if you wanna talk to him in his present state of mind, go ahead. Let me know how that turns out." Melinda snapped, using the wall to push herself to her feet. "And you! Aren't you meant to be working on that spell?" she turned to her brother, hands on hips.

"Already done." he produced a bit of paper from his pocket and waved it in front of her. "It's like I already knew the words." he added thoughtfully.

"What spell?" Adam demanded, looking between them. "What the hell are you planning?" A loud roar prevented any possible reply and a Mercury Demon appeared in the doorway.

"Yeah, orbing now - yelling later." Melinda said, seizing Adam and Chris's hands and disappearing in a flurry of white and blue orbs just as a blast singed the wall where they'd been seconds before.
