Heidi E.Y. Stemple didn't want to be a writer when she grew up. In fact, after she graduated from college, she became a probation officer in Florida. It wasn't until she was 28 years old that she gave in and joined the family business, publishing her first short story in a book called Famous Writers and Their Kids Write Spooky Stories . The famous writer was her mom, author Jane Yolen. Since then, she has published more than thirty-five books and numerous short stories and poems, mostly for children. Heidi lives and writes on a big old farm in Massachusetts that she shares with one very large cat who lives inside, a dozen deer, a family of bears, three coyotes, two bobcats, a gray fox, tons of birds, and some very fat groundhogs who live outside.

Once a year she calls owls for the Audubon Christmas Bird Count. Eugenia Nobati was born in 1968 in Buenos Aires, Argentina, where she still lives with her family. She started as a graphic designer in 1990, but in 1997, she decided to dedicate her time exclusively to illustration, mostly to children's books. Over the years, her work has been published in nine countries and more than fifty books.
