The Necroscope Series

A mix between supernatural novel, spy story and thriller best describes Brian Lumley's popular Necroscope series. Mixing genres like Lumley does can be a risky business but he does an excellent job of it.

Harry Keogh is a Necroscope who speaks to the dead. His incredible talent is put to use in a confrontation with vampire Thibor Ferenczy and his human tool Boris Dragosani, part of a russian spy agency. The Cold War constitutes the background for the series.

Lumley's main strength as a writer is probably his plot. These books are very well written and appear to be carefully planned.

The first book in the series, Necroscope is probably the best, the second volume, Vamphyri! is arguably the weakest. The following three books maintain a high quality and develop the universe of Lumley's vampires greatly. There is some blood and gore, but it never dominates the story. I would rank this series as the ultimate vampire saga.
Highly recommended!
