This book is the Approved Edition by the Apostolate of the Precious blood and contains an imprimatur by Bishop Ayo-Maria Atoyebi from the Diocese of Ilorin, Nigeria where this particular devotion began.
We also have this book by Queenship Publishing. Here is a simple comparison between the Queenship edition and this book (Nigeria Edition):
+This Item listed here appears to be the official book approved by Bernabe, the Apostolate, and Bishop Ayo from Nigeria
+The Queenship edition is easier to use because it is spiral bound but does not seem to have official approval.
+The Content is almost identical in both books.
