Labyrinth
It started with an artifact; it always did, and this one was just as destructive as most. They had faced danger many times before, but Myka, trapped inside the Goblin King's crystal balls (oh dear, better not say it like that to Pete) with a brilliant time-travelling author had the feeling this was the last danger they would face, this was her last chance, this was the last time she'd ever see H.G Wells again.
So she kissed her.
It wasn't the end of the world, after all. It turned out to be the start of something much better.
