   Summary

   A chaotic coven of vampires has somehow managed to become something resembling a dysfunctional family.

   The coven includes Agatha, the maniacal Bellatrix, its reluctant organizer Narcissa, her sister Andromeda, and newborn vampire Hermione Granger, a former hunter.

   Rio Vidal was a hunter too.

   Eventually, Rio finds herself pulled into the coven and all the madness that comes with it.

   With vampire hunters breathing down their necks, supernatural trouble closing in, and certain coven-mates going on increasingly unhinged benders...

   Will any of them survive the chaos?
