John Masters is a forgotten author in many ways, which is a real shame as his writing is wonderful. He was a career army officer and many of his novels use his experiences of army life as a basis. He has a fantastic appreciation and understanding of the difficulties of life for locals and those serving in the army. His books are primarily based around army life and even if you are not a military fan, don't let this put you off. A number of novels have India as the location from the time just before the mutiny until after independence. They are brilliantly written and follow the trials and tribulations of an army family whose name is Savage. They are fiction based on fact and are very exciting reading.
I first came across John Masters when in my teens - some thirty+ years ago, I was completely enthralled. Sadly, many of his books are no longer in print, which is a real shame. Those still in print are primarily classed as military and recall his personal experiences of army life. But novels such as Nightrunners of Bengal, Bhowani Junction and The Deceivers, are fiction using actual events as a basis and I can highly recommend them - if you can manage to find them!
