I think I’ve always wanted to be a writer, even before I could hold a pencil. My parents were great storytellers, so bringing characters to life seemed as natural as riding horses bareback, which I also grew up doing. I won my first writing contest as a 10-year-old tomboy. My 50 words on “Why I Want to Be Batboy for the Kansas City A’s” won first place, but the team wouldn’t let a girl be batboy. It was my first taste of rejection.

Since then, I’ve had over 400 of my titles published for children and about 25 for grown-ups, with millions of copies in over a dozen countries. I write for every age and in nearly every genre. I keep busy doing school visits, keynoting at conferences, and writing from rural Ohio, where I enjoy our family, including horses, dogs, cats, & a changing array of outdoor creatures.
