Bill, the Galactic Hero: Planet of the Hippies from Hell [EPUB ebook] 

BARWORLD! For all the years that BILL had served in the Troopers, with all the hard beds, hard heads and no creds, any booze on offer was probably embalming fluid, or worse. BARWORLD! An assignment there promised bubbly, brandy and beer galore — enough to give BILL’s right arms (both of them) at last some idea of just what they were for. But that was before Uncle Nancy’s Cross-Dressing Emporium. And the Time/Space Resonation Nexus. And the Hippy from Hell. They were enough to completely alter a person’s perceptions of reality. And, like, totally bum him out.
