Where did you get the idea for your most recent book?
I had Cally's voice from the start. She was fun to write and I loved her bravery and pride in her work. For Rick, I'd watched a documentary on psychopaths, and then read some books on the subject. I was really interested to learn that very successful business people tend to score very high on the psychopath test. I knew I had to get these characters together... and Cally's sneaking into The Monster seemed perfect!
