A girl is entrusted with a very special box yet given little information on its use or implications.
When almost-middleschooler Gwendy meets the suited man, she is strangely drawn to the box he offers. She needs to have that box! But then he's gone, and she's left with a million questions and one strange, small box with a series of colored push buttons on top.
This is my favorite kind of Stephen King story: it's creepy and sinister, yet really left up to your imagination to fill in the blanks. Because what's scariest is very personal, and you create your own nightmare with his subtle framework and direction.
Also, this audiobook recording includes a bonus short story, "The Music Room," based on an Edward Hopper painting. Also fantastic, and very, very minimal.
