After reading Eon, I could not wait to get my hands on the follow-up.. . and in some ways "Eternity" came through better than I hoped.
There are some really clever twists and plot threads in this novel, but in the end it fades away rather than fulfilling the promise of the first book. There is also some great writing through the first two thirds of this book, but you may feel the last third leaves you wanting more. Great ideas abound in this novel, but they never seem to reach the climax the reader anticipates.
There is plenty of room for yet another sequel, but the story seems to work hard to quickly tie up any loose ends, just in case Greg Bear decides not to go beyond Eternity. If you liked Eon, read this novel, but be prepared a different intensity level.
