Carolyn Strom Collins and Christina Wyss Eriksson grew up reading the Little House books. Hoping to answer some of their questions about Laura and Little House, they visited every Little House site and museum and did in-depth research on Laura and her family. The result is The World of Little House. Both authors live with their families in the St. Paul-Minneapolis area of Minnesota, about a four-hour drive from where Laura lived in On the Banks of Plum Creek. In addition to writing The World of Little House, they are also the authors of My Little House Crafts Book, The Anne of Green Gables Treasury, and The Little Women Treasury.
