Accacia's Curse (Sisters of Hex: Accacia #1)

Born with a rare blood disorder that means she cannot go out in daylight, Accacia has learned to live in the dark, even if it has been incredibly lonely. Determined to find a cure that will finally allow her to walk in the sun, Accacia has spent her days and nights holed up in her laboratory doing just that.
After a freak encounter with a tall, dark and ridiculously handsome stranger, Accacia might just have found her cure, but not in the way she expected. Drawn into a parallel world of paranormal creatures and a Queen who wants her dead, Accacia has to put her trust in three vampires who, seemingly, want to devour her in more ways than one.
Accacia's Curse is book one of Accacia's trilogy and part of the 'Sisters of Hex' paranormal romance series.
Five sisters, five clans, a curse and whole host of supernatural creature.
