The night eternal

"It has been two years since the Master?s plan succeeded and a near apocalypse coated the world in eternal darkness. Now able to roam freely, the Master?s legion of vampires rule the world?a horrifying police state where humans are harvested for blood. As humanity despairs, Dr. Ephraim Goodweather and an unlikely team of heroes continue their fight against extinction, hoping to unlock the secret to the Master?s demise." -- from publisher's website.
