Slaka! Land of lake and forest, of beetroot and tractor. Slaka! Land whose borders are sometimes here, often further north, and sometimes not at all! Rates of Exchange tells the hilarious story of Dr Petworth on his cultural exchange to the small (and fictional) Eastern European country of Slaka. Palid and middle-aged, Dr Petworth might appear stuffy, but during his short stay he manages to embroil himself in the thorny thickets of sexual intrigue and love, while still finding time to see the major sites. Shortlisted for the Booker Prize in 1983, Rates of Exchange took Bradbury’s satirical gifts to a new level.
