Where did you get the idea for your most recent book?
I wanted to try writing a dark tale of redemption. Flannery O'Connor has called the murderer in her story A Good Man is Hard to Find the character most capable of redemption in that story. I always found that idea curious though I understand her thinking behind it.
As far as actually redeeming an evil character, well, I have seen other writers attempt it and wanted to see if I could do it as well or better. The jury is still out.
