$35/case
CASE NO. 002
The Friend Behind the Couch
Nora's little brother has a new imaginary friend, and he's very good at hiding. Nora knows the friend's name, which is strange, because she hasn't said it out loud in eight years.
$35/case
CASE NO. 003
The Girl Who Waits at the Crossing

CASE NO. 004
The Wax Museum on Route 12
The wax museum has one rule: keep moving. Stand still too long, and something else finally gets to move instead.

CASE NO. 005

CASE NO. 006
The Board Game Nobody Wins
A board game from a yard sale FREE box has a second piece that isn't anyone's — and every turn taken moves it closer to the finish.
$35/case
CASE NO. 007
The Kid in the Class Photo

$35/case
CASE NO. 008
The Scarecrow in the North Field
The family farm has one rule that's never been explained, only followed. This year, the reason finally comes out.
$35/case
CASE NO. 009
The Sugar House at the Edge of Miller's Woods
It isn't always there. When it is, the smell is impossible to resist — and so is everything else about it.
$35/case
CASE NO. 010
The Shadow Trade
Some trades were never meant to be permanent. Sam only meant it as a dare. Somebody else has been waiting a very long time to finish it.
$35/case
