From time to time readers have asked how the covers to my novels come together. What you see above is the original proposal for Corridor of Darkness, the first book of the series, designed by Gabrielle Prendergast. Its evocative imagery convinced me to choose her creative services for all three volumes of the trilogy.

AND IN CASE YOU MISSED THE ANNOUNCEMENT…The final volume in the Corridor of Darkness trilogy, FULCRUM OF MALICE, is now available in both eBook and trade paperback at Order Fulcrum of Malice
Patrick W. O'Bryon 
I guessed the model for the cover of Beacon and feel certain the persona for Fulcrum’s cover is no other than the first Dr. O’Bryon……am I close? Now enjoying volume 3…. 🙂
You hit it on the nail head, Ken! Thought it fitting for him to make a personal showing in the final volume, since his adventures inspired it all.
