The Night of the Witch by M Woodruff

When seventeen-year-old Lena Beckford hears the lock turn in her bedroom door she begins her nightly ritual to honor the moon. But instead of seeing the usual visions from her father, the flame, she’s contacted by her grandmother pleading for Lena’s help after she’s been buried alive in the Strangers’ Graveyard. As Lena begins her search she meets two witches, like herself, who promise to help her find her grandmother. One is a ridiculous old crone who seems to be leading her around in circles, and the other is a seductive man she’s immediately drawn to. But she can’t quite seem to escape from either of them when she realizes they're armed with their own devilish motives, which blur the lines between friend and foe, sanity and insanity. Is it murder Lena must commit, or justice she must serve, to finally free her grandmother from the darkness of the grave?
