The original, classic, Dark Shadows books from the Paperback Library, return with Hermes Press' archival reprint of all 32 titles in the series beginning with the first novel which first saw print in December, 1966.
The twenty-fifth book in this reprint series is titled Barnabas, Quentin and the Magic Potion. Each book in the series was written by William Edward Daniel Ross who used the pen name Marilyn Ross.

Barnabas predicts trouble for Collinwood when Nicholas Freeze, in whose antique shop Carolyn Stoddard works, discovers a centuries-old potion that promises eternal youth. Soon after, Mr. Freeze's daughter Hazel, tricked into taking the serum, dies. Carolyn is grief-stricken over her friend's death. Barnabas insists she stay on at the shop to watch Nicholas Freeze and his associates, one of whom Carolyn suspects is Quentin Collins, back at Collinwood in a disguise.

Then Carolyn sees Hazel's ghost.

She interprets this as a warning that Mr. Freeze has marked her for his next victim. Barnabas still refuses to let her quit.

Has Barnabas made a fatal mistake by deliberately endangering Carolyn's life? Or will his plan avenge Hazel's murder and put her spirit to rest?
