Some years ago I wrote and illustrated a nonfiction picture book about the life cycle story of sea turtles that was published by Doubleday. Tracks in the Sand had a starred review, multiple printings, and was named an Outstanding Science Trade Book by the National Science Teachers Association. But like most books, it eventually went out of print and could only be found in libraries or perhaps a used book store.

The funny thing is, the sea turtle life cycle has not changed in millions of years...
