The Arrival by Shaun Tan
Shaun Tan is a ridiculously talented Australian writer-illustrator. This 2006 book The Arrival is one of the most original books I've ever seen; telling its story entirely through pictures, it has the feel of an old, dreamlike, silent movie like Metropolis or The Cabinet of Dr Caligari.
The story concerns an man who leaves his own country in search of a better life in a strange new place. We see him struggle with language, customs, technology, plants and animals, which are utterly foreign to him. He meets other immigrants and hears their stories, and he works to be reunited with his wife and daughter. If that sounds dull, don't be put off! It's scary and sad and hopeful and whimsical and funny. And every page is a lush visual experience.
