There have been a fair few weak ‘celebrity novels’ written in the wake of a successful memoir that made them famous, though. (Though they’ve often tanked!) The one that comes to mind is Petite Anglaise — does anyone remember her? English blogger living in Paris, whose very popular anonymous blog got her fired from the accountancy firm she worked for, even though she never named herself or it until she was outed by a UK tabloid afterwards, when she took her former employers to a tribunal (and won damages).
She (real name Catherine Sanderson)) got a two-book deal from Penguin (as it then was). The first, a memoir, sold well, I think because it had all the stuff that had made her blog popular (living, working and dating in Paris, being a single mum to a cute small child, explaining aspects of Parisian life, billed as ‘Bridget Jones in Paris’ etc.)
The second, a novel about much the same thing (mildly chaotic single English mum dating in Paris, but with a completely different job substituted), didn’t do well, because she just couldn’t really write fiction. Plus I think that what her readers liked about her blog is that it was true, whereas the novel was just rather tired autobiography we’d already heard, masquerading as fiction.
I suppose my point is that Penguin, realising she’d used up all her life experience likely to be of interest in her first book, thought enough people would read a novel about the same shtick if it was by her. I don’t think it did well.
Isn’t it possible PRH thinks it’s worth a punt that readers engaged enough with the ‘Raynor Winn’ brand to keep believing through all the revelations will follow her into fiction?
The snag is that, like Catherine Sanderson, it would have to hit the same beats as TSP to engage the readership. Nature, indigene, spousal devotion, everyone else treating them badly, miracle recovery etc.
