"What do you do when the enemy is bigger than anything you’ve ever known? What do you do when powers beyond all understanding conspire to destroy all? You do everything you must. Desmond Miles has spent every moment since his capture working to understand his past. Who are the Templars really? What does the order of Assassins have to do with the The First Civilization – a group seemingly from the distant past, and their insistence that the end of the world is coming? With the Apple of Eden in hand, Desmond and his friends go to their new hidden base and try to discover how they will stop the predicted solar event that threatens to destroy all life on Earth. Once again, the key to the future lies in the past."
