The halls were empty. Charlotte had missed the first bell and would be late, again. Her homeroom teacher would ask her for an excuse and she would say, 'Overwhelming feeling of dread.' That was going to go over nicely.

But if you were Charlotte, and you had been feeling that life was some cosmic joke that had no punchline, and in the space of a moment you had gone from being Charlotte-without-a-kitten to being Charlotte-with-a-kitten, you too would have found it nothing short of remarkable.

This morning, as Charlotte approached the brick facade of Hartnett, she found herself overcome with a great sense of dread. It hit her with a strange and sudden force, and she had an overwhelming urge to turn back, get into bed and not go out for about three weeks. She stopped in her tracks. The feeling itself was alarming to Charlotte - was she sensing something? Something dangerous? And was it something supernatural or just middle school? Sometimes it was hard to tell the difference.

Jack believed in something—he believed in white witches and sleighs pulled by wolves, and in the world the trees obscured. He believed that there were better things in the woods. He believed in palaces of ice and hearts to match. Hazel had, too. Hazel had believed in woodsmen and magic shoes and swanskins and the easy magic of a compass. She had believed that because someone needing saving they were savable. She had believed in these things, but not anymore. And this is why she had to rescue Jack, even though he might not hear what she had to tell him.

People feared snowstorms once. Hazel read about this all the time. Pioneers opened their front doors and saw they'd been entombed in snow overnight. They walked across malevolent swirling whiteness and did not know if they would survive. Nature can destroy us in a blink. We live on only at its pleasure. That was what looking at the witch was like.

Hazel had read enough books to know that a line like this one is the line down which your life breaks in two. And you have to think very carefully about whether you want to cross it, because once you do it’s very hard to get back to the world you left behind. And sometimes you break a barrier that no one knew existed, and then everything you knew before crossing the line is gone. But sometimes you have a friend to rescue. And so you take a deep breath and then step over the line and into the darkness ahead.

If shadows were caused by the interplay between light and Life, a child's was still forming. An adult's was inextricably bound to his body, but a child had a tenuous relationship to his own permanence, and thus, his own shadow.
