The Fanged and The Fae by Melissa Marr

The three Faery Bargains novellas in a book length collection (also available in paperback & hardcover).

“Blood Martinis & Mistletoe” (Set after book 1)
Half-dead witch Geneviève Crowe makes her living beheading the dead–and spends her free time trying not to get too attached to her business partner, Eli Stonecroft, a faery prince in self-imposed exile in New Orleans.
A walking-dead relative and a deadly but well-paying job make the holidays a lot more complicated than anyone needs. With a killer at her throat and a blood martini in her hand, Geneviève accepts what seems like a straight-forward faery bargain. Eli’s terms might make the holidays a little more bearable, but if she can’t figure out a way to escape this faery bargain, she’ll be planning a wedding soon.

“Daiquiris & Daggers” (Set after book 2)
A fun spa weekend away with friends in a city free of monsters, what could be better? Gen’s necromancy had been on the fritz, so a recharge sounds perfect–until she arrives in San Diego to discover that either the spa is too steps beyond weird or there’s magic afoot

“Champagne & Commitments” (Set right before book 3)
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.
