Endymion: A New Phase of the Hyperion Story
Endymion occurs approximately three centuries subsequent to the events in Hyperion and Fall of Hyperion. It showcases a predominantly new set of characters. The climactic events of the previous book have such far-reaching consequences. For instance, the closing of the far-casters, the end of the hegemony, the disappearance of the Shrike, and the rise of the Pax due to the cruciform. Simmons has thus crafted a highly novel and distinct galactic environment to frame his equally intricate and elaborate space opera epic.
Although Endymion might lack some of the mythic undertones of the first duology, it compensates with a fully developed narrative. This narrative meticulously extrapolates the repercussions of the previous books and continues the underlying struggle and mystery involving the Core, AIs, and the humans and Ousters caught in the middle. Dan Simmons is unafraid to reshape his own elaborate universe while treating it as a natural extension of the earlier story. Just like the first two books, Endymion is merely one half of the story. Therefore, you must be prepared to commit to reading both books to obtain the full vision as Dan Simmons intended.
