I grew up in the Midwest, child of a schizophrenic father and a hardworking single mother. I read everything I could in the school and town library, and discovered science fiction in second grade, starting with Tom Swift books and quickly moving to Heinlein juveniles and adult science fiction. When I was twelve, I discovered the collection of city telephone books in my local library. I pretended I was doing a paper and called Isaac Asimov; we spoke for a long time, and he sent me a postcard encouraging me to write. So thank you, Isaac, wherever you are, for being so kind and generous with your time. Robert Silverberg had no time for that kind of nonsense... I studied computer and cognitive science at MIT, and wrote programs modeling the behavior of simulated stock traders and the population dynamics of economic agents. Later I did supercomputer work at a think tank that developed parts of the early Internet (where the engineer who decided on ’@’ as the separator for email addresses worked down the hall.) Since then I have had several careers-real estate development, financial advising, and counselling. I retired from financial advising a few years ago and have done some work in energy conservation (ask me about two-stage evaporative coolers!) and relationship issues. My books on attachment theory have done well enough to try fiction again, and the Substrate Wars series is the result.
