The challenge (easy level) is done, and it has been fun. The books I read were all quite different from one another.
The European book was a historical novel by Turkish author Orhan Pamuk, The White Castle, about two men from different cultures who switch identities. It garnered 3 stars.
The North-American book was a surrealist novel by Guatemalan author Miguel Ángel Asturias, the outrageous Mulata de tal (The Mulatta and Mister Fly), which I gave 3 stars.
The African book was a slightly magical but mostly realistic novel, Ways of Dying by South-African author Zakes Mda, which I gave 5 stars.
The South-American book was The Tunnel, a psychological thriller by Argentinian Ernesto Sabato, which I gave 5 stars.
The Asian book was Red Sorghum, a historical novel by Mo Yan, which I gave 5 stars.
And the Australasian book was another historical novel, Oscar and Lucinda by Peter Carey, which I gave 4,5 stars.
I am happy with my choices and would, given the opportunity, read more books by all six authors.
