The Lion and the Deathless Dark by Carissa Broadbent

In a world plagued by divine war between humans and vampires, Kyrene scrapes by as a bounty hunter, bearing a blessed sword from the goddess of justice. But when she suffers a devastating loss, she kills the very goddess she had been sworn to serve in a fit of rage – making her a target to gods and mortals alike.

When a vampire prince offers her survival in exchange for one final job – to slay the gods themselves – Kyrene is set on a path of vengeance. Septimus is calculating and silver-tongued, but worst of all, he sees more of her than she wants to reveal. Together, they must take down the ultimate marks, all while
navigating a web of prophecies, secrets, and curses. But their growing connection is most dangerous of all when it could jeopardize Kyrene’s ultimate goal: to betray him and kill the goddess of vampires, even if it means sacrificing love for revenge.

The Lion in the Deathless Dark is a compulsive dark fantasy from Carissa Broadbent, and the first book in the Bloodborn Duet, the fifth book in the Sunday Times bestselling Crowns of Nyaxia series.
