Valence

In this cold city, people can shrink to 1 mm. From the age of 16, a person develops the Shrink.
Kew, whose real name nobody knows, makes large snow globes for 1 mm-people, escapist snow globes where time stands still and you remain young. For a 1 mm person, one year is a regular person's 10 years. Shrinking is banned, because of how it messes with time. But in Kew's hideout, these snow globes let people shrink and choose a world to spend the rest of their lives in. Stocked with a handful of rice, you'll have food for the rest of your life.
Kew himself hasn't shrunk in 4 years. Nobody knows why he can't.
Lita, 16, wants to save her little brother, who is afraid of dying. She'll do anything to get him a spot in a snow globe, but things aren't that easy. For one, he's only 13. But she's heard of Kew. They say he can do impossible things. He can cure diseases, make magic and freeze time, they say. She may have even seen it.
So, she only needs to strike the perfect bargain.
