Ashes and Grave by Aiden Bates and Jill Haven

I don’t normally deal with nasty ghosts, but when Nix needs help, I’m the only one qualified. His dragons are under attack, and it’s up to me to stop it. But Nix isn’t making it easy. He seems determined to hate me because I’m a necromancer, and he wants nothing to do with the attraction smoldering between us.

This specter isn’t a random haunting, and its connected to both Nix and me. We’re going to have to work together to defeat it, but if Nix finds out how I’m connected, any trust I’ve built with him will go up in smoke.
