The Night Eternal

The Night Eternal is a 2011 vampire horror novel by Guillermo del Toro and Chuck Hogan. It is the final novel in The Strain Trilogy, which began with The Strain and continued with The Fall.

Two years have passed since the vampires, led by the Master, used atomic weapons to create a nuclear winter, blocking the sun almost continuously and allowing the vampires to move freely, except for 2–3 hours when sunlight filters through. The vampires have restructured society as a police state. The strongest and most influential humans have been exterminated; and those spared are used as slaves, while the infirm and weak have been herded into camps to harvest their blood.

A few survivors continue to resist the vampire occupation. Epidemiologist Dr. Ephraim Goodweather grows distant from his friends: the Master, now occupying the body of rock star Gabriel Bolivar, has adopted Goodweather's son, Zach, as his protégé and is grooming the boy to be his next host body. Goodweather's lover, Dr. Nora Martinez, leaves him for exterminator Vasiliy Fet. Following his friend Abraham Setrakian's death, Fet struggles to decipher the Occido Lumen, a tome possibly holding the key to defeating the Master. He is aided by Mr. Quinlan, the Master's vengeful half-vampire son.

Flashbacks to biblical times reveal the vampire race's origins: the seven Ancients, including the Master, arose from Ozryel. Ozryel was an archangel of death, one of the three angels that God sent to destroy the cities of Sodom and Gomorrah for their wickedness. Ozryel was overcome with bloodlust while the cities were destroyed. God punished him by having the other archangels cut his body into seven pieces and scattering them across the Earth. Over time, Ozryel's blood leaked from the burial sites and became sentient, thus spawning the Ancient Ones. The Master was spawned last, from Ozryel's throat, and so was referred to as "the Young One" by the other Ancients.
