Author's Comment: Q. What was your inspiration for the 'Children of the Lamp' series?
P.B. Kerr: Inspiration is a word I try to avoid. I never really feel inspired. When people talk about inspiration, I think of it as a little creature in the garden I go to see and grab to try to get it. Instead, I am a compulsive writer. I write every day.
I think of myself as Rembrandt when he painted 'The Feast of Belshazzar.' In this painting there is a hand with nothing attached to it that is writing on the wall. I think of myself as that writing. I hand write everything the first time. I do not type or work on a computer. The most portable writing system is a pencil and paper. [Source]
