Chris L. Demarest says: "A few years ago my wife and I brought our two-year-old son to an open house at a fire station. Ethan loved the big red fire trucks and I became totally enthralled not only by the trucks, but by the idea of serving my community as a firefighter. "Being a full-time illustrator, I work at home, so I could be on call at any time. I took a lot of classes, passed some hard tests, and became a volunteer firefighter. I am on call for the Meriden, New Hampshire, station, where I now get to drive those big red fire trucks. "I created Firefighters A to Z to show Ethan and other children what firefighting is really like. It can be an exciting job, but it's also a dangerous one. I hope to convey that through this book."
