LeAnn Rimes and songwriter Darrell Brown have written a companion book to their song "What I Cannot Change," which appears on Rimes' current album, Family. Also titled What I Cannot Change, the 128-page text and photo book is published by HarperStudio and is scheduled to go on sale April 14. Promotional copy describes the book as "stories from people who have experienced their own journeys of change." A CD of the song is included in the package. Brown co-wrote nine of the songs on Family as well as the Keith Urban hit, "You'll Think Of Me." Among the promotions attending the book's release will be a 25-city radio satellite tour and a tie-in with Mother's Day festivities.
