Now available in Portuguese under our Ember Publications imprint Avestruzes e Canários: O Adventismo em Transição (1966–1979), the authorized translation of Gilbert M. Valentine's seminal work on the recent history of Adventism. According to renowned Adventist historian George Knight: 

​

"The most important contribution of Valentine's pioneering volume is its highlighting of the terrible cost of avoiding facts. His extensive treatment of Adventism's intellectual struggles in the 1960s and 1970s features the dynamic of a church in the midst of unwelcome change. All future endeavors in coming to grips with Adventist history during the mid-to-late-20th century will of necessity have to begin with Valentine. This is a book of crucial importance for all those seeking to understand current issues in the church, wherever readers happen to fall in the denomination's continuum of thought."
