Viviana has always lived dangerously, spending her nights in the Ruby District of the City of Eternity, mingling with vampires and indulging in the wild nightlife of the Eastern Zone. But when her best friend, Thana, mysteriously disappears during one of their midnight outings, Viviana's carefree existence takes a dark turn. Desperate to find Thana, she ventures deep into the vampire territory, seeking answers from shadowy figures who offer only cryptic warnings and empty promises. As forces from every side try to stop Viviana from uncovering the truth, she must confront dangerous enemies, unravel the mystery of Thana's disappearance and understand her role in a dark prophecy. Trapped between two worlds - one of ruthless vampires and another of rebellious humans - Viviana finds herself entangled in a conflict far larger than she could have imagined. In Blood & Lust, the second book in the City of Eternity series, Viviana's quest to rescue her friend will lead her into a web of betrayal and revolution-where no bond is unbreakable, and even loyalty can be deadly.
