Who? is the first in a series of five books (Who?, What?, When?, Where?, and Why?) focused on preschool and early elementary-aged children and the questions they ask.

Its rhythmic, melodic prose and smile-inducing illustrations delight young and old alike while encouraging the quest for knowledge. Posing fun and sometimes silly questions to the naturally curious young mind stimulates the intellect and opens whole new realms for exploration, critical thinking, and creative problem-solving. Who? teaches that learning is an adventure as we actively engage with a world just waiting to reveal its secrets and our special place in it.
