Bloodwars

Nestor and Nathan Kiklu are twins, united by blood and by a psychic bond inherited from their father, Harry Keogh, the Necroscope. Once so close each knew when the other breathed, they have become the bitterest of enemies, divided by the terrible evil of the Wamphyri.
Nestor, now a vampire Lord, rules a portion of the great tower known as the Last Aerie, from which he and the beautiful but deadly vampire Lady, Wratha the Risen, hunt the humans once defended by the Necroscope.
Nathan, flung through the Gate to Earth, discovers that he shares not only Harry Keogh's ability to talk to the dead but his power to travel effortlessly and instantly through space and time. Joining forces with Britain's E-Branch, a super-secret organization of psychics, Nathan returns to the vampire world to save his people.
Nathan desperately seeks a way to redeem his twin, but despite the solace he finds in the arms of his childhood sweetheart, knows his fight with Nestor must end in death - and the death of all the vampires. Blood - both living and undead - is spilled as Earthly weapons are brought to bear against the metamorphic alien Wamphyri., ISBN13: 9780312856793 ISBN10: 0312856792 Material Type: hardcover
