In a February 2007 web chat on her web site, Grant discussed a book she was working on titled Mosaic: Pieces of My Life So Far, saying, "It's not an autobiography, but more a collection of memories, song lyrics, poetry and a few pictures." The book was released on October 16, 2007. In November, it debuted at No. 35 on the New York Times Best Seller list. In the same web chat, Grant noted that she is "anxious to get back in the studio after the book is finished, and reinvent myself as an almost-50 performing woman".
2007 was Grant's 30th year in music. She left Word/Warner, and contracted with EMI CMG who re-released her regular studio albums as remastered versions on August 14, 2007. Marking the start of Grant's new contract is a career-spanning greatest hits album, with all the songs digitally remastered. The album was released as both a single-disc CD edition, and a two-disc CD/DVD Special Edition, the DVD featuring music videos and interviews.
Grant appeared with Gill on The Oprah Winfrey Show for a holiday special in December 2007. Grant has plans to appear on CMT, a Food Network special, the Gospel Music Channel, and The Hour of Power.
