Her first book, In the Tall, Tall Grass, was published by Henry Holt and Company in 1991. According to one library summary, "Rhymed text presents a toddler's view of creatures found in the grass from lunchtime till nightfall, such as bees, ants, and moles." It was critically well received and its sequel, In the Small, Small Pond, was a runner-up for the 1994 Caldecott Medal.
