Charming and pretty Biddy Forrester lives in China with her parents, medical missionaries who bring healing to the bodies and souls of the Chinese. Because of the poor climate condition, Biddy has to leave China and return to England with only one Friend, the Lord Jesus, and with a little green frog, her most valuable and cherished possession.

Biddy knows the meaning of a surrendered life—and lives it! She wants always to please God, to trust Him, to walk with Him, to give Him her all. She brings warmth and light to a cold, dark England, witnessing, with her childish simplicity, everywhere she goes.

In simple faith she asks God for the money for a hospital which her father needs in China. Then she puts her faith to work, giving her all to the Lord, even her little green frog. Her radiant testimony wins many hearts to Jesus, and brings in all the money needed for the hospital. The Little Green Frog displays the power of prayer, and the price and purpose of true Christianity. A wonderfully wholesome book.
