Kill Me Quick. QuickSilver, #1

The pirates of Charleston's Golden Age aren't as dead as you might think. In her centuries-long life, Kulika Yadav has chalked up more than her fair share of regrets. Deserting the crew of former pirate king Bartholomew Roberts is not one of them. She vowed she would never return to his Charleston mansion, knowing that doing so would mean captivity or death. Now, two hundred years after she left, she has no other option: her new master is dying, and the person who holds the key to his cure has disappeared on Bartholomew's turf.
But Kulika isn't the only woman on a mission in South Carolina. Patience Quick has been searching for her best friend for six months now, along with enough other missing people to fill a whole deck of cards. She's willing to do just about anything to find her friend, even if it means following a midnight lead to a colonial-era mansion, where a never-ending pool party is about to turn sinister. While Kulika knowingly confronts the man who gave her immortality, Quick is left scrambling to understand the nature of the creatures whose nest she has unwittingly disturbed.
When the two women's paths cross, blood will fly. Kill Me Quick is the first book in Josie Jaffrey's QuickSilver series, a sapphic dark fantasy series set in Charleston, South Carolina.
