A child's laugh should be the butterfly wing, the ripple-maker, for all the world. There are many children crying. We hear them echoing from news media. It is time to pray the change of the world in children's laughter. More than one hundred themes and issues crucial to hope and justice were crowd-sourced to create this collaborative anthology of fifty-two reflections from seventy-seven writers in eleven different countries. These writers offer background, prayers, liturgy, questions for action and reflection and now invite readers, both individual and small groups, to join the community.
