In 1988, at the peak of her fame for playing the glamorous villainess Alexis Colby on "Dynasty," Joan Collins released the first of several novels. While writing was not new to the actress—she had published a successful autobiography and account of a family crisis—fiction was uncharted territory and the province of her younger sister, mega-bestselling author Jackie Collins. Many articles, including a piece by Dominick Dunne in Vanity Fair, hyped the potential rivalry between the sisters. Reading "Prime Time," it is clear to see there was never a threat. The novel follows Jackie Collins' successful formula of the doings of the Hollywood haves- and have-nots, with a crazed stalker (a staple of Jackie Collins) thrown in. What makes "Prime Time" fun, and lends it a certain authenticity, is that it concerns a night time soap opera--here called "Saga"--and the race by various actresses to play its villain. The reader has a good time wondering how much of a roman a clef "Prime Time" is, which seems to borrow certain subplots from its real-world counterpart (a young actor replaced early on; domineering producers; a closeted actor who becomes ill with AIDS). Certainly its accounts of the nuts and bolts of being on set and filming seem absolutely convincing and based on Collins' own experience, as the feeling of being considered washed up after 40. Collins shares her sister's slightly breezy tone and dry wit, suggesting a family characteristic, albeit in a less well-developed way. The novel's ending seems rushed and runs out of suspense and steam; and Collins eventually abandons all characters but her heroine, but in the meantime, it zips along and the guessing games of what is truth and what is fiction make it an amusing example of the type of escapist glitz, sex and shopping novel that seems to have vanished in the 21st century.
