As an investigative reporter I usually got to pick my subjects and then it was up to me to do something with them. As an author I've been doing the same thing: writing about subjects that I want to know more about. First it was American history, then physics, now it is biology. Each time, it has seemed as if I'd fallen down Alice's rabbit hole into a world of fascinations. Right now, it's genetics and evolutionary biology that have me in their thrall. I'm convinced that reading (and then writing) about serious subjects is a key to breaking the literacy glitch in some of our schools. Who wants to read easy stuff?
