I'm fairly certain this is:
The Miles Between

ugh, this sounds so familiar. I read everything I could find about witches, as a kid in the 70s and 80s. ZKS was a favorite, too. I'll keep thinking on this one and will poke around some more.

Hmm. I did a little searching and came up with these two other possibilities. I'm not sure if either of them is your book, but both seem to also feature girls playing at witchcraft:
The Seven Stone (republished as Maggie in the Middle)
I Will Make You Disappear

Tab's guess is solid. I'll also throw out:
The Active Enzyme, Lemon Freshened Junior High School Witch and
The Headless Cupidboth from that same era, both about young girls playing at witchcraft.

LOL, I used to be a children's librarian. Read it so often in storytime I still have the darn thing memorized from beginning to end.

I mean, it's not really a rebus if they're doing it that way, but it seems like a reasonable guess, given the clues.

Where the Wild Things Are. (Max wears a wolf suit and makes mischief, gets sent to his room, a forest grows, a boat sails by and he goes to the land of the wild things where they make him King of All Wild Things, and when he gets home his supper is waiting for him, and it's still hot.)

Yay! I'm glad you found it. Hope it was as good as you remembered!
The Living Dead 2 for the link. Glad you found it!

Kris, I noticed the thread changed to solved a few minutes after I posted my suggestion. It wasn't I who changed it, so presumably it was Lauren?
Zombies: The Recent Dead has a story by Max Brooks, so maybe?

No worries. It's a bit confusing until you get used to it. I'm happy to help!

Ellie, don't delete the thread, someone else might be looking for this book and find this thread helpful! I will take care of moving the thread to Solved if you like. :)
