When we 
last heard from my project of reading the Hugo-award winning novels, I was at #22.  I recently added #23 and #24.
I looked at the 
list of novels and decided to read the most recent one I hadn't read.  That would be 
Forever Peace, by Joe Haldeman, the 1997 winner.  But I knew that Haldeman's 
The Forever War had won the 1976 Hugo.  Thinking that 
FP was the sequel to 
TFW, I decided I needed to read them in order.
Well, I was wrong, but that didn't matter.  
Forever Peace was another novel on the same subject as 
The Forever War, but in a different setting.  The subject was war.  I enjoyed them both, although 
The Forever War suffered from a goofy idea of what life would be like in the early 21st century.  
Forever Peace suffered from being too much of a cyberpunk novel -- I don't buy the whole 
nanotechnology hype.
On the other hand, 
TFW is the only SF novel I've ever seen that sets a section in the adjacent town of 
Hyattsville.
