One Yellow Daffodil' is both a look to the past and to the future and expresses my belief in the great spirit and strength of our children.

I write about people I think are interesting, and then I discuss it with my editor, and she decides if she thinks it will be interesting to children as well. If I have no great interest in the subject, I find the work to be terribly boring. And if I find the person interesting, I love the research part and, by extension, the writing as well.

I love math and was a math teacher for many years, so it was fun for me to write several math books, including 'Fraction Fun,' 'Calculator Riddles,' and 'Shape Up!' 'Fun with Triangles and Other Polygons.'

I love to write. I used to be a math teacher. And I like the idea that other people could write about the same subjects, but no one would write it just the way I do. It's very individual: a child could write the same story as somebody else, but it wouldn't come out the same.
