Professor Romano Amerio, episcopal consultant to the Central Preparatory Commission of the Second Vatican Council, has written in Iota Unum what may be the very best book on the pre-Council, the Council, and post-Council.

At the same time, Amerio's book is accessible to the average layman who is interested in understanding the growing confusion which seems to have infected the Church since the Council met in its first session. If St. Athanasius is correct in stating that "At the time of judgment, no one will be excused for not knowing that which one should have known," then every Catholic should read this book.
