In Spindlehollow, traditions are everything-especially the week before the Full Pumpkin Moon.

That's when every child leaves an offering on their doorstep: a treat, a trinket, or something handmade. Why? To keep the Unseen Three from visiting. No one's ever seen them. No one remembers how the tradition started. But everyone follows it.

Except this year, someone forgets.

Now, kids are waking up missing strange things: voices, shadows, even their names. Whispers fill the alleyways. Old rules begin to surface. And at the center of it all are three figures who aren't supposed to exist.

Patches and Ziggy know spooky, but this isn't just a prank gone wrong-it's a curse. And if they can't uncover the truth behind the Unseen Three before the Full Pumpkin Moon rises... Ziggy might be next on their list.

Some monsters knock.
The worst ones don't have to.
