Not in a hurry to read this book. High price is because it is affiliated with university publishing house.  If it were published for the masses, it could be available for a 1/3 of the price.  From the review, too much in-house squabbling. This is what the newbies  have in common with tradition of RCC.  
Like Southern Baptists, they multiple by dividing.  This seems the paradigm for Christians in toto. The Christian scriptures have no copyright. Get a copy, start a Christian church.  Franchises are free.
The peculiar emphasis of this book are those Christian churches who seem enthralled by apostolic succession. Ironically, Jesus wasn't that kosher.  Only an honorary rabbi.
He emphasized worship in spirit and in truth (Jn. 4:24) and wherever 2 or 3, boys and girls gather. (Mt. 18:20). 
The human search for tribe, belonging, community is the constant tradition, apostolic or otherwise.
