My books are based on the “what if” principle. “What if you became invisible?” or “What if you did change into your mother for one day?” I then take it from there. Each book takes several months in the long process of writing, rewriting, writing, rewriting, and each has its own set of problems. The one thing I dislike about the writing process is the sometimes-loneliness of it all. Readers only get to see the glamour part of a bound book, not some of the agonizing moments one has while constructing it.
