Set in the 1960s, Meg Harrison leaves her native Minnesota for New York to pursue a career in acting while working as a Playboy Bunny in New York's Playboy Club. After changing her name to Morgana Harriott, she soon lands the role of Margie, a restaurant waitress and daughter of a local artist, in the new daytime TV serial Dark Passages. The show will eventually feature a vampire, but the catch is that Morgana is one in real life.
The characters described on the sets of Dark Passages resemble quite vividly those on Dark Shadows and the actors who played them. The diner set where Margie works is greatly similar to that of the Collinsport Inn restaurant on Dark Shadows.
For the back cover, Jonathan Frid wrote the following blurb: "Reading DARK PASSAGES was like being back on the sets of DARK SHADOWS, except with real vampires behind the scenes!"
