RE: The Fall of Hyperion by Dan Simmons

The whole Cantos is some amazing worldbuilding. Universebuilding, even. I would only spoil that the next two will be easier to read and to love, with other unexpected turns that were probably to be expected as the baseline. And the final one which was larger in volume, The Rise of Endymion will be quite revealing and inspiring. Keep on reading!

Then you can hop to Dan Simmons's next universe. Still awesome.
