Absolutely. But honesty is a moral category. Not one relevant to advertising, an industry whose job involves selling things they don’t need to the public, whether that’s fast food, fridges, skincare, or ‘feelgood’ books.
A book can absolutely be honest or dishonest, but that’s on the author — advertising/marketing surrounding that book is aimed at making someone pick up that book from a table in a bookshop rather than the other books adjacent to it. SW signed a contract to say TSP was what really happened, so that’s what marketing went with. They weren’t looking for proof or problems, any more than skincare advertising worries about the 20% of users whose rosacea wasn’t improved by RandomCream.
Would TSP have sold equally well if SW had made no such claims about blamelessness for losing their home? If she’d been frank about narrowly escaping criminal charges? I think it might. If TW’s illness had been presented as ‘some worrying symptoms not yet diagnosed’? Probably not. Not because I think the actual book would be substantially changed by either, but because it would have been far less marketable, and may not have been picked up so soon or at all.
Jenn Ashworth’s The Parallel Path (novelist walks Coast to Coast path after Covid to get away from caring responsibilities, with a dying artist friend writing to her about his own dying at every stop, while her own physical symptoms turn out to be something serious) is a much more ‘honest’ book, in the sense of being a thoughtful, often challenging and uncomfortable read, where the protagonist doesn’t present herself as in any way admirable, doesn’t finish the walk, and doesn’t give the reader any neat resolution. It’s excellent, by a critically-acclaimed novelist, and was respectfully reviewed.
But I had only vaguely heard of it before someone recommended it on a previous thread, despite being a wide reader who routinely reads the broadsheet book review pages, the LRB/ TLS, browses in bookshops, keeps up with new releases etc. It didn’t have a ‘hook’, it isn’t ’feelgood’, the cover is unmemorable. It’s a difficult sell.
