Redemption Song — Karen Mercury

When five college friends reunite, one night changes their lives forever. Halloween in New Orleans. Remy Lafitte has paid a charlatan to enact a Voodoo ceremony in the cemetery. The ritual reanimates Niko Valdes, a French Quarter tutor who was damned to Everlost for murdering his sister's attacker. Mild-mannered stockbroker Heidi Purdue stumbles upon Niko and Remy in a compromising position. They are interrupted by a demon on horseback who beheads the charlatan before giving the trio a pentalpha puzzle to solve. Curvy Heidi knows that heartthrob Remy would never fall for her, but she falls for the undead tutor. Remy, jealous of the other two's closeness, agrees to an equitable menage, opening up to a male lover. The centuries-long battle against primordial evil leads them to a temple, where they find Solomon's ring. They go past the portal of Hellmouth to redeem themselves, but the real puzzle is how to fulfill the prophecy that they are intertwined inexorably - now and forever.
