Author Robie Harris and illustrator Michael Emberley have worked closely together to create nearly a dozen age-appropriate books for children and teens on human development and sexuality, including It’s So Amazing!: A Book about Eggs, Sperm, Birth, Babies, and Families (Candlewick, 1999)and It’s Perfectly Normal: Changing Bodies, Growing Up, Sex, and Sexual Health (Candlewick, 1994). For Harris and Emberley, the entire research process is of the utmost importance when it comes to creating accurate informational books. From finding the right resources to portraying information in word and illustration, these two have insights to share about the inquiry process.
