Beyond the shadows of any known forest grows the Goblin Oak, an enormous tree lit by hundreds of glowing jack-o'-lanterns. All the spirits and strangeness of Halloween come from the Goblin Oak, but a mysterious magic threatens to destroy it.
Meanwhile, Amber's stuck at home having the worst Halloween ever, until she meets a trio of professional, pumpkin-snatching goblins. Facing a Halloween night of handing out candy, Amber joins them as they use tricks, cobbled-together gadgets, and teleporting pumpkin cars to snatch more pumpkins and strengthen the Goblin Oak.
But the Goblin Oak grows beyond the reach of any map or compass, and is protected by the brambledark: a shifting mass of shadow vines that makes people lost in the woods, or makes them forget their way entirely.
To find the Goblin Oak and to save Halloween, Amber must abandon the familiar and become truly lost.
Kris Bowser has spent her life adventuring in the rocky hills and forests of Southern New England. Goblins taught her how to sneak into the other worlds that exist tucked into corners and around bends. Though Kris is in a rebel band of superheroes and outcasts, she is often caught in the dystopian clutches of Mundane Problems, and must send her characters to do her adventuring for her.
She lives with her partner in an old mill town, haunted by the spirits and shadows of machines and industry.
