Yumi and Painter, "practical" artists in two different cultures become somehow bound to each other such that they experience each other's worlds.

This story took me a little while to get into, and required a fair amount of "let me explain what is going on..." from the narrator to understand some Cosmere concepts that in other books/series are meted out more slowly.

Still, I enjoyed the characters and their self-exploration as well as the imaginative world.
