The book, Reading Quirks, was published in English and is now available.

Andrés de la Casas Huertas and Javier García del Moral wrote the book’s 72 four-panel comics. And artist Laura Pacheco illustrated it.

Even Dallas’ own Ben Fountain, author of Beautiful Country Burn Again, wrote an endorsement for it: “Reading Quirks is a work of nonfiction. You have in your hands an anthropological study of a strange and far-ranging human tribe, a tribe that gets from the reading of books the kind of happiness that other people derive from wrestling alligators.”

The hardback book costs $20.
