A Head Full of Ghosts' was my first full horror novel, and that felt like coming home as a writer.

After my debut didn't go very well with Holt, I needed to be in a healthier head space. I was happy to emerge from there. You will always have those negative thoughts as a writer, but you can't let them take over. If you let them take over, those are the real page killers.

As an adult, I've learned to cope and pull the plug on the worst what-ifs before my mind takes me to a place from which I can't return.

I have to admit to being a music snob. I think, in a parallel universe, I pretty easily could have been Jack Black's character from 'High Fidelity,' working in a record store and snidely commenting on everyone's purchases.
