Transformers: Exodus tells the tale of how Orion Pax became Optimus Prime and how the great war between the Autobots and the Decepticons began. It should be noted that this books is an adaptation of the game War for Cybertron and has elements from the episodes of the original Generation One pilot More than Meets the Eye and the later second two episode where a group of Autobots travel back in time to witness the beginning of the war. But this book also has elements of the Megatron rising story line as well as the War Within story line. I recommend this book to any Transformers fan who like me grewup with Generation One and enjoyed the following Generations and the movies and I am looking forward to reading the next book in this duology.
