The Last Sunrise

The shield is gone. The planet is dead. They are the only thing keeping the spark of humanity from going out entirely. When the Taupo supervolcano tore the earth open, it didn't just trigger an ice age-it manufactured an apocalypse. Wrapped in the suffocating twilight of the Gloom, a toxic blanket of sulfur and ash has permanently blocked the sun. For the world's hidden vampire covens, this perpetual night seemed like a paradise.
But the victory was a mirage. Without sunlight, global agriculture collapses, and the human race begins to rapidly starve. Realizing their food supply is marching toward extinction, the vampires must step out of the shadows to take control. Dr. Lara Williams is a cynical, gritty agronomist who watched her family freeze to death in the ruined subway tunnels of Chicago. Captured by vampiric scouts while scavenging dead seed banks, she is dragged miles underground to Sanctuary-9-a massive, hydro-powered military silo converted into an agricultural fortress.
There, she is given an ultimatum by Warlord Valerius, a pragmatist who views humanity not with malice, but as an endangered, delicate ecosystem that must be managed. To save the remaining human population from a creeping biological blight, Lara must forge a symbiotic blood pact with the warlord and engineer Triticum nocturna-a weaponized, violet-scaled "Night-Wheat" that thrives in absolute darkness.
Locked in a high-stakes psychological war with her captors, Lara hides a genetic kill switch inside the crop, turning the pasture into a cage that cuts both ways. In a world where freedom is an extinction vector and captivity is the only ark left, Lara must decide how much of her humanity she is willing to rewrite to ensure there is a tomorrow.
