Wendy Pfeffer is the author of many science-oriented children's books, including From Tadpole to Frog and A Log's Life, which won the Giverny Award for Best Children's Science Picture Book. An early-childhood specialist, she enjoys visiting schools and teaching creative writing to children. She lives with her husband, Tom, in New Jersey, where the change of seasons allows them to sail and swim in summer, then cross-country ski after the winter solstice welcomes winter each year.

Linda Bleck grew up in a family of nine children in northern Illionois, and their Thanksgiving feasts were celebrated at a table her father made from a large door. Today, Ms. Bleck is making memories with her own children in Wisconsin, where the fall's brilliant colors of changing leaves and crisp blue skies, as well as visits to local fruit and pumpkin farms, provide her with the inspiration to create her vivid illustrations. She is the author and illustrator of Pepper Goes to School and the illustrator of a series of children's treasuries of nursery rhymes, songs, lullabies, and prayers. Ms. Bleck has a degree in graphic design from the University of Illionis, Urbana-Champaign. She lives in Wisconsin with her husband and two children.
