This months book of the month is NightWhere by Bram Stoker Award-winning author John Everson.
"She yearned to go beyond... but some curtains should never be opened.
When Rae broached the idea of visiting an underground sex club, Mark didn’t blink. He should have. Because NightWhere is not your usual swingers club. Where it’s held on a given night…only those who receive the red invitations know. Soon Rae is indulging in her lust for pain. And Mark is warned by a beautiful stranger to take his wife away before it’s too late.
But it’s already too late. Because Rae hasn’t come home. Now Mark is in a race against time—to find NightWhere again and save his wife from the mysterious Watchers who run the club. To stop her from taking that last step through the degradations of The Red into the ultimate BDSM promise of The Black. More than just their marriage and her life are at stake: Rae is in danger of losing her soul..."
"A master of twisted imagery, Everson doesn’t shy away from graphic gore: Nightwhere is an erotic horrorfest you won’t be able to put down!” - Lucy Taylor, Bram Stoker Award-winning author of
