Two types of people will like this book: Hippies/wannabe hippies and Sci-Fi fans.
Some people like to read about them hippies. This books is pratically a textbook for hippie slang, hippie music, hippie clothes, hippie's nicknames for drugs, hippie lifestyle. It does not sugarcoat any of it. It just tells it like it was. Poor Starbright (aka Susan Stein) runs away from the Cleveland suburbs to find her friend Penny Lane (aka Nance Jones, aka Crinky) in the Haight-Ashbury section of San Fransisco in 1967. Along the way she tries LSD, gets pregnant, gets an abortion, drops the mod look, picks up some new vernacular, goes to enough concerts to make you jealous, and ends the book a hippie. People who like to hear about that stuff will like this book.
Some people like reading about time travelers. They want to hear Chiron Cat's Eye in Draco tell five hundred years of history from the perspective of 2467. They want to hear about him consulting the computer on his knuckletop to find whether the Prime Probability has collapsed. They like when he uses his maser and explains Cosmicism. They like the descriptions of tachyportation. They'll love this book too.
Like, wow, man, the WHOLENESS of the universe that I glimpsed while tripping on...uh...this book tells me to, like, tell ya this book is really groovy and I bet you'll really dig it, y'know what I mean??
