Dan Simmons' third installment in the Hyperion series, "Endymion," is hardly comparable to the previous two. No longer do we have the broad, sweeping storytelling from the Hyperion Cantos, but instead, we are presented with a relatively narrow plot following the adventures of a couple characters. Rather than a sci-fi version of the "Canterbury Tales," "Endymion" is simply an adventure novel. If that was all you really liked in the first two books of the series, you will probably agree with several other reviewers who have criticized this book for its smaller scope and different style.
However, Simmons' writing still retains its fluidity and rich style. The characters are still well-crafted and engaging, the plot remains just as intriguing, and Simmons again shows his remarkable knack for creating rich and believable worlds.
Like the first two novels in the series, "Endymion" and its sequel "Rise of Endymion," are really almost two halves of a single book. While "Endymion" does not have the abruptly unsatisfying end of "Hyperion," its story is certainly incomplete. The real value of this novel is that it lays the groundwork for its sequel, the capstone of the four-book series, and the true jewel that makes the Hyperion saga stand out as one of the greatest science fiction works written.
