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 per cent 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.
"She's very proud of the book," said a source.
She reportedly had discussed the book at length with the singer's former business partner Marc Schaffel last week.
The Thriller hitmaker died of drug overdose June 25 last year.
