Hyperion is an astonishingly imagined monolith of a book. Set 700 years after the 21st century, mankind lives on multiple planets across the galaxy. The characters & plot are spellbinding to the point that reading this book is pure pleasure. The prose is punctuated by poetry, especially that of poet titan Jean Keats. And the best part of all this? There's a sequel titled The Fall of Hyperion.
"The Canterbury Tales" in space! Seriously, each character's story is detailed and engrossing in a different way, and the differences make the overall narrative stonger. Cons: While the immediate sequel is equally excellent, the more recent follow-up novels (Endymion etc.) are terrible.
Absolutely incredible story telling. The idea of having seven narrators is far from new, but they weave a portrait of a decadent utopia that has to fall. Action packed, and best villain of the genre. Cons: It's not a con, it a warning : every great book has to be 'earned' by its reader.
