Valeria Tepes, wife of the infamous vampire Lord Vlad Tepes, finds herself on a distant planet, centuries after her initial encounter with her dark lord, and must now protect her new home from a human oligarch. Her whirlwind romance with Vlad began in colonial Spain and led them through Eastern Europe before fate transported her to Planet Tepes. Now, in the year 2100, a law clerk named Leon Parker is sent to her planet upon her request, unaware that his life will be irrevocably changed by their meeting. Valeria draws him into her world of blood, desire, and the fight to keep her planet safe from the encroaching human oligarch Erick Von Helle, whose ambitions extend far beyond Earth and Planet Tepes.

The premise suggests a narrative blending historical romance with science fiction elements, focusing on themes of power, desire, and interspecies conflict. The erotic undertones, as indicated by the subtitle, point towards a mature audience seeking intense romantic and potentially violent encounters. The story appears to explore the enduring nature of vampiric existence across time and space, contrasting ancient power with future human ambition. The introduction of a human protagonist into this established world sets up a dynamic of discovery and potential transformation.
