One that kinda bogs down in the middle Is "Ill Wind" I can't remember the Authors, but it's about a bacteria that eats all the plastic.
Another good SF is Stirlings series that starts with "Dies the Fire" The Protector's War" and "Meeting in Corvalis". All good reads. My only problem with Stirling is he writes about how difficult it is to make a longbow but nothing about how hard it is to make straight arrows.
