Guardian of Wrath (Nyx Fortuna, #6)

Kiev A-Morridahn must pay.

This is the vow Nyx Fortuna has sworn. Keeping it is all but impossible, but it is the one thing that motivates her. Whatever she must do, she will do. Whatever she must sacrifice, she will give.

But if she succeeds, she'll have to reckon with everything she's pushed aside in her quest for vengeance. As it turns out, feelings—and friends—don't like being ignored.
