1001 Dark Nights is a series of 12 books being released this year (one per month). They are written by 12 different popular authors. The books have a loose associated with the Nights and seem like they are being marketed as steamy romances akin to the 50 Shades of Grey series but also have a vampire one, a cowboy book and one with detectives.
Shayla Black, author of the volume Forever Wicked, describes her book at USA Today (http://www.usatoday.com/story/happyeverafter/2014/02/13/1001-dark-nights-novella-collection-graham-folsom-adrian/5444107/). She describes the story as "When her billionaire husband blackmailed her for a honeymoon, she stole his heart" and about her hero - "Jason Denning is one sexy, clever Dominant who's determined to win back his wife."
