Has anyone made a list of leftist books for readers of different age-groups?

We all know children should read Das Kapital in the original German when they're 12, but apart from that, what books or leftist cartoons should they be learning at different ages.

Age 4-8

Some Zapatista/Subcommandante Marcos books of fables

Age 9-13

???

Age 14-16

The Ragged-Trousered Philanthropists
