Assassin's Reincarnation

Nyx Wolf was tired of her daily dose of danger, blood, and death. She has been living such a life for 20 years after being sold to a crime syndicate only to be trained and honed as a deadly assassin that no one can take down. But not because she excels at such a profession doesn't mean she likes every bit of it. She wants nothing of it anymore. She wants to stop. And that's how a mere action fantasy novel she stumbled upon one night of messing with her phone between an assassination job, became a big help. She fucked up and died. Only to wake up in a body of a twenty-year-old girl, who has eye-catching bright red hair, and a husband who clearly doesn't care about her at all.
