This is a well-researched book about the critical time between Vatican II and the publication of Humanae Vitae. Many of the characters are familiar (at least by name) to those who lived in that era, but the interactions were quite unknown to me. What seems most important to me at the end of the book is the way the commission members found themselves changing positions as they pursued to Pope's commission to provide him with the best advice they could. We know how the process played out, what a wrench HV threw into the workings of the church, but we gain insight into the non-reception of the encyclical from the commission's own deliberations.
