Initially I was reluctant to buy this book because I was looking for books about contemporary Peru when I first went there in 1997. Inca Kola was written in the late 80s, when Peru was on the verge of collapsing into chaos and civil war, and the political situation was completely different from now or even the late 90s. I thought a book from the 80s would be hopelessly dated.
However, I eventually bought it after my third trip to Peru, and found it to be a delightful account of visiting a country I'd come to know a little, and love a lot.
Yes, some things have changed dramatically since Parris's trip. The political and security situation is far, far better, but serious poverty, inequality and racism remain. So much of what Parris writes about is instantly recognisable. Peruvian culture won't change in a hurry and neither will the people - warm, incredibly hospitable and nosy, utterly cavalier and irresponsible in dealing with regulations and authority.
Much of Parris's book is timeless, and most of the rest is a fascinating account of visiting Peru at a time when no sensible tourists wanted to go there. It's a delight to read.
