The Secret of the Blue Glass

In a dusty library, in the quietest corner of a house in a Tokyo suburb, live the Little People: Fern and Balbo, Robin and Iris. Just a few inches high, sleeping in cigarette boxes and crafting shoes from old book jackets, they need only one thing from their Humans—a nightly glass of milk, served in a sparkling Blue Glass goblet, by a trusted young member of the Human family.

But when World War II comes to Japan, bringing a dangerous new kind of patriotism, both Humans and their beloved Little People face a world they could never before have imagined. 9-year-old Yuri Moriyama has just taken on the mantle of milk-deliverer, following in the footsteps of her brothers, parents and aunt before her.
