Rudyard Kipling's 'Actions and Reactions' is a collection of eight short stories and poems published in 1909. While some may find the stories difficult to follow due to their references to British colonialism and outdated language, the writing is top-notch. Some of the titles include 'The Four Angels', 'The New Knighthood', and 'The Puzzler'. Though there isn't a specific theme running through the stories, they are all classic Kipling, making for an enjoyable read.
