This weeks book recommendation is The Forever War by Joe Haldeman. First published in 1974, this book quickly became a staple in science fiction. I first read it a few years ago and was surprised at how relevant the story remains. A lot of early science fiction becomes dated when trying to predict the future. Even some science fiction written today falls victim to the exponential growth of technology, but The Forever War is a well written novel that succeeds in its commentary on the human race. Its predictions may never come to pass, but they are not dated and are intriguing. Some of them may actually be more relevant now than they were in 1974.
If you like science fiction, check this book out. The use of time dilation is fairly accurate and incredibly well used to tell the story. Traveling at the speed of light can do crazy things to a person. Specifically the way it effects their lifespan in comparison to others.
