'Changes in Latitudes' began when I was looking at a photograph of a sea turtle swimming underwater. I had such a strong feeling for the beauty of this ancient creature, at home in the sea. On the spot, I wanted to swim with that turtle. I began to imagine a character who would do just that.

Seven of my novels take place in the Southwest, in the Four Corners area which has been my home since 1973. I know these mountains, rivers, mesas and canyons well, so it's been natural for me to draw on my own personal experiences here.
