We Only Have Forever

"He is in my care. I won't let you take him." I grit my teeth, and try to let him know I mean business. I step away from the intimidating man and use my body to block the stairway.
"What's done is done, Rebecca. You made the wish. I am here to grant it."
"But you can't! You can't...because..." I'm struggling for words, knowing how this works. He's right. I should have been more careful what I wished for.
But it's not like I meant to make a wish in the first place!
The Goblin King sits impatiently, waiting for me to make up my mind.
What am I going to do...
How did the girl in the story get out of this...
A deal!
"I want to make a trade!"
"Oh?" he responds, amused. "What could you trade me that I would want?"
Okay, so, maybe I didn't think this far ahead.
"You could... you could..." I lower my gaze and I try to figure something out. "I... I have money...?"
"I don't want your paper. I don't even like the people on it." He yawns. "Can't you think of something more interesting, Rebecca?"
Fuck.
Yeah, I guess I should have seen that coming.
"You could... take me, instead." I cringe at the corny 'Beauty and the Beast' line that just came out of my mouth. Why does this disturb you more than the fact that you just OFFERED YOURSELF TO THE KING OF THE FUCKING GOBLINS??
"You would offer yourself in the place of a little boy who isn't even related to you?" He leans closer, making me uncomfortable. Oh geez...

....

Thirty years after losing Sarah to her clever words and completion of his Labyrinth, Jareth the Goblin King hears a call. A wish that he must grant, but the wish has not come from Sarah's lips. Instead he comes to find sixteen year old Rebecca, an artist whose parents are forcing her to go to school to study medicine to become like them. When Rebecca realizes that she made the wish while holding the Labyrinth book, she must offer something of value to Jareth or lose the little boy whom she is babysitting to the Goblin King.
