It is a bright, busy summer and ten-year-old Cathy Leonard is full of exuberance, exuberance for the strawberries that want picking, for the children's library which will meet at her house, and for her friend and boarder, Naomi. But when Naomi's mother decides that if they cannot find their own home in town they will leave for New York, Cathy's bright summer becomes suddenly clouded. With fierce determination she tries to find a home for Naomi, her tactics alternating between childish stubbornness and adult practicality. At last a home is found and during the process Cathy has taken the first tentative steps toward maturity. Those who have enjoyed Cathy's adventures in the author's A will find here that same warmth and understanding of the pre-teen age world, told wholesomely and with enthusiasm.
