Starship troopers

Starship troopers(1959) is a rather controversial work of science fiction and something of a classic. Our world is at war with an alien race resembling large insects and the war is not going well. A young man decides to join the mobile infantry instead of studying as his parents expect him to. He is soon promoted and has a successful military career. But will humanity be able to win the war ?
Starship troopers is not all action, it's more of a thinking man's book with quite conservative moral views. Some of the ideas I feel are antiquated, the book is getting old, but I did find it an interesting read.
