I've just finished a couple about Brighton from their wilderness years where they almost fell out of the guff FL
Build a Bonfire by Stephen North which is about owners who thought they could turn their ground into a retail park (hmmmm) pretty amazing story of how the fans fought back.
The other was Gullhanger by Mike Ward which from someone who does the TV reviews in the Daily Star was surprisingly good and quite funny (a bit guffy mind)
I lived down that way for a while so always looking out for books about guff lower divisions and Non League.
Got Wheres your Caravan a while back (think someone recommended it) so that's my next trip reading sorted.
