In the "don't judge a book by its cover" department, Prince's 21 Nights (Atria) is large and glossy and purports to document his 2007 sold-out UK tour. Instead, it features glamour shots of the Artist wearing designer clothes, tonnes of makeup and jewellery while posing in various five-star hotel rooms. A handful of shots include beautiful women, some dressed as maids, others as geishas - though we don't know why. The accompanying poems are just as vacuous. This barely works as a coffee-table book, let alone a memoir.
