RTW: What does your character hide in their underwear drawer?

...or other secret location.

We borrowed this prompt from Carolyn Mackler's presentation on creating characters, which several of us attended at LA SCBWI, and loved!

This was harder than I thought it would be, to be honest. Some of my characters are just not that into hiding things, others have nothing they need to hide. But here we go:

From SO DEAD:
-Olivia: I'm sure if I dug deeper I could think of something else, but the first thing that comes to mind is the letter she hides in her diary (in the story).
-Grayson: Anything he felt he needed to hide, he would destroy or throw out. Having a secret item hidden somewhere in his room would make him too uncomfortable.
-Olivia's brother, Taylor: His room is so messy that his mom avoids it whenever possible, but I think he would probably hide things like condoms and boy magazines in his underwear drawer, just in case (and maybe an issue of Cosmo he bought to try and learn more about girls...)

From UNTHAWED:
-Emma: Doesn't have many possessions to hide, or really any privacy at all. But she does hide poison inside a mattress.
-Dusty: A book he stole. Haven't figured out exactly where he'd hide it, though (again, lack of privacy in this world) but he's resourceful. He'd find somewhere.
