For one, I wrote this quite a few years ago, before the cancer with its surgeries and chemotherapies. Yet I find I remember a great deal about this book. Color me mildly surprised. Its interesting how deep some things run.
Second, I am very amused to see how my tropes repeat themselves. I already know about this. We all do it. In my case, I write about lost boys, mechanical men, hidden underground tunnels, layered truths, self-discovery, and oddball animals. There are elements of Other Me that to my eye clearly tie back to Mainspring, to Green, to Trial of Flowers.
I don't think I'm plagiarizing myself. I do wonder a bit if I am repeating myself. On the other hand, should I be writing de novo every time I launch into a story? I find myself wondering where the balance lies between repetition and novelty.
Got no answers, but got more questions. Ah, the writing life.
