Champagne & Commitments by Melissa Marr

Half-dead witch Geneviève Crowe makes her living beheading the dead–and trying to make sense of accidentally ending up a faery princess when she ended up bonded to Eli Stonecroft, a faery prince in self-imposed exile in New Orleans.

But bonded for eternity isn’t enough for family and friends–of her future citizens. It’s time to plan a wedding ceremony.

Unfortunately there isn’t enough champagne available to deal with an undead-great-grandmother, a faery king who’s trying to romance Gen’s assistant, and a city where Halloween is a holiday worth dying to enjoy.
