London's Jane Addams is one of the few who can honestly challenge us with such a question. She dared as a girl to turn her back on London society and to face the slums as her own background. Through this book, she brings us face to face with life's tremendous contrasts around the globe, -- China, India, Japan, Europe, the America's, Africa and the Pacific Islands; she views the suffering, the starving, the fighting and struggling millions. And throughout she rings one triumphant note, one power can overcome it all, through unflinching dedication of individual lives to a real experience of the living God. Such faith and courage as Muriel Lester's motivates spiritual dynamite, and this book honestly faced, should blast the most complacent from their seats.
