Sallow Manor - Mónica Benítez

A wave of corpses, their injuries defying explanation.
Two women, bound by love in the past, and two entangled in the present.
A perplexed forensic expert and a mysterious woman, a cipher to all.
Astrid's once placid life shatters when she becomes the coveted prey of Gabriel, the nation's most ruthless vampire. Power clings to him, and there's someone hungry to snatch it away. Unbeknownst to Astrid, she holds the key to tipping the scales in either direction.
Survival hinges on locating Victoria, the sole individual privy to halting Gabriel's reign. In this quest, she enlists Ynea, her mother, and Irene, a forensic specialist thrust into a perilous and enigmatic realm she's unsure about joining.
Their shared mission: eliminate the most bloodthirsty killer humanity has ever known.
