Old Man’s War, the 2005 debut novel from science fiction writer John Scalzi, is an immensely entertaining sci-fi space opera. The breezy narrative style and compelling plot make this book a quick and fascinating read. Told from the first person point of view of John Perry, a 75-year-old widower from Ohio who decides to join the Colonial Defense Force and defend Earth’s colonies from a host of alien threats, the novel follows his ‘alteration,’ training and combat deployment to various worlds. There’s nothing truly groundbreaking about this novel, Scalzi had an interesting idea and developed it into a very entertaining story. It’s somewhat annoying how the main character always seems to be the smartest person in the room, and manages most of the time to complete missions without too much difficulty. There is not much tension or suspense in how the plot unfolds. Still, Old Man's War is a solid novel that entertains. B+
