A much-anticipated memoir by the estranged father of Scientology leader David Miscavige is coming out this spring.

St. Martin's Press told The Associated Press on Wednesday that Ron Miscavige's book is called "Ruthless: Scientology, My Son David Miscavige, and Me." It will be released May 3.

The elder Miscavige was with the church for more than 40 years before leaving in 2012. The publisher says his book will provide "a riveting insider's look at life within the world of Scientology."

"Ruthless," which was first announced last year, is expected to be the latest in a wave of unflattering works about the church, including the book and documentary "Going Clear" and "Beyond Belief: My Secret Life Inside Scientology and My Harrowing Escape," a memoir by David Miscavige's niece, Jenna Miscavige.
