London, June 20 (IANS) Michael Jackson’s mother is planning to release a book in the memory of her late son on his first death anniversary.

Katherine, who inherited 40 percent of her son’s estate and was named the guardian of his three children, will release a picture book called ‘Never Can Say Goodbye: The Katherine Jackson Archives’ Monday, reports contactmusic.com.
