So far in March I have finished reading two nonfiction books. The first was lent to me by a member of my family; the other came from a second-hand book sale.
Underland: A deep time journey by Robert Macfarlane is a demanding book to read. I began it in January and finished reading it early in March. It is very wide-ranging both in the places described and their geology. Macfarlane has spent time with experts in various fields and had adventures in the landscape above and below ground to provide the content of Underland. His descriptions are vivid. The lessons from history and the warnings about the future do not make for an enjoyable read, rather a disturbing one. It is a book worth reading.
The Secret Life of Bletchley Park: The WWII Codebreaking Centre and the Men and Women who worked there by Sinclair McKay is a fascinating account of a bygone pivotal age. It is entertaining and informative with many quotes from people who were involved, some of whom have written their own stories. The timeline of the Second World War runs through the book, which ends with the opening of a museum on the site.
