Jermaine Jackson will tell "the truth as we know it" about his brother Michael in a new book.
The singer said the book, called You Are Not Alone: Michael, Through A Brother's Eyes, would commemorate the life of the star who died in June 2009 at the age of 50.
The book will also cover the 2005 trial which saw Jackson accused of sexually assaulting a child and the circumstances around his death.
Jermaine said: "We don't want Michael's life -- or death -- to be an eternal mystery. This is the truth as we know it. I have read so much about what people think they know about Michael, but this is about what really happened."
