Che Guevara's Motorcycle Diaries gives an account of the six-month-long journey through South America which crystallised his political commitment. He was accompanied on that journey by a young doctor, Alberto Granado, and this book is Granado's own version of their eye-opening trip through Chile, Peru, Colombia and Venezuela. Granado was as changed by what they saw of Latin American poverty and injustice as was Che, though it led him in a less glamorous and high-profile direction, confirming his commitment to fight suffering through medical rather than political means. First published in Spanish in 1978, it's more than just a further memoir for Che completists. Interest in the book will no doubt be boosted by Robert Redford's movie based on the Motorcycle Diaries, also due for release in December.
