Prince will add "author" to his music and acting resume with the arrival of "21 Nights," a book based on his 21 sold-out concerts last August at London's 02 Arena.

Due this fall from Simon & Schuster imprint Atria Books, the work is described as a "photographic essay" that offers "a rare glimpse into the life, lyrics, and mystique" of the artist.

"Juxtaposing his dueling worlds of music and solitude, it will incorporate Prince's evocative poetry and lyrics to new songs and other selections, and 124 full-color, sumptuous, never-before-published images by celebrated photographer Randee St. Nicholas," Atria announced Monday.

"21 Nights" will also come with a CD of after-hours jams, "Indigo Nights," unavailable from any other outlet, reports the AP.
