Elif Batuman is a regular New Yorker contributer, and once upon a time also studied Russian literature at Stanford. The Possessed: Adventures with Russian Books and the People Who Read Them is a fun collection of essays recounting her experiences as a grad student. She takes us from Stanford to Tolstoy's estate in Russia all the way to Uzbekistan. This humorous take on a life with books is a delight for anyone who survived grad school or has a soft spot for Russian literature.
In the mood for something less light-hearted? Try Alexandra Fuller's stunning Scribbling the Cat. Fuller grew up in what was Rhodesia, and then Zambia. Though living in the US, married, with two small children, she returns to her parents' home in Zambia. There she meets this man, who she calls K, a veteran of the wars in Rhodesia/Zimbabwe and Mozambique. She hatches a plan that they will travel back into Zimbabwe and Mozambique, that through this he may exorcise the past, and she will understand it, understand this war that was the backdrop for her childhood. The result is an intense look at the scars of war, and of a section of the world that all too often flies below our radar.
It's not quite the same as getting on a plane yourself, but a great way to take yourself away for a few hours at a time.
