Tale of the Necromancer by Kathryn Ann Kingsley

Now she knows her past. But is it one worth living with?
As Marguerite finally learns the terrible truth behind what she is—and why Gideon Raithe needs her—the memories of her past come flooding back. As she travels through all her previous lives, she learns she has been running from a decision the entire time. And now, she has nowhere left to hide.

Is her life one worth living? And despite how she has come to feel about Gideon, can she forgive him for all that he’s done?
Or are some things worth leaving in the grave?
