[4] Frustrated former hippie novelist Sandy Blair becomes involved in the investigation of the brutal murder of rock promoter Jamie Lynch, whose heart had been torn from his body.

[5] Lynch had managed several bands, including the legendary rock group the Nazgûl (named for the evil Ringwraiths in Tolkien's The Lord of the Rings).

With Lynch out of the way, a disastrous act of arson forces the remaining three members of the Nazgûl to go on a reunion tour, promoted by a rich man named Edan Morse.

[5] Interviewing the surviving members of the band while tracking down his old friends from the 1960s, Blair meditates on the meaning of the flower power generation as he crisscrosses the country.

He eventually becomes the Nazgûl's press agent and is soon swept up in the frenzy of their successful reunion tour and an oncoming supernatural convergence, whose nature he must uncover in order to solve the murders of Lynch and Hobbins.
