Deathbringer

Inga Alenir is a Swordbearer. She is the latest in a long line of women to inherit a magical weapon called Deathbringer. She's also dead, murdered on her wedding day by the ruthless and covetous noblewoman Yenda Avard, who steals the sword after killing Inga and her entire family.

And yet, some secrets won't stay buried. Deathbringer has a will and a consciousness of its own, and even has the power to raise Inga from the dead for a short time. It warns her that she has one week to find and retrieve the sword before death reclaims her—permanently. With each day bringing her doom and final demise ever closer, Inga will have to see just how far she's willing to go to achieve her vengeance.
