When I started reading for myself, I was voracious about it. The Lord of the Rings series was a huge favorite. I pored over them. Something about the bravery and self-sacrifice enthralled me to the point that I read the entire thing aloud to my little brother (with a few canny deletions of endless descriptions of forests). At about age ten, I discovered the Sherlock Holmes mysteries, and I've been obsessed with those ever since. It turned out that hero stories are my mojo.
We grew up in the Pacific Northwest, so we pretty much had free rein of the neighborhood. My parents were always careful, but the town was safe, so we put pennies on railroad tracks to flatten them and sailed Lego men through dyke tunnels and fostered families of mice we found in the meadow. If we weren't reading tales of adventure, then we were out running amok imagining our own.
