The North Road is one of those books that’s very difficult to categorise. Superficially, it’s fairly straightforward: a non-fiction book about Britain’s ‘Great North Road’, a 400 mile stretch that has existed in some form or other since Roman times, now known (for the most part) as the A1(M) motorway. Yet from its earliest pages, it’s clear that it’s a little more complex than that.

The Möbius Book is a neither straightforwardly Lacey’s fifth novel, nor entirely not. It is a work in two parts, one ostensibly fiction and the other memoir, in its printed form designed to be read in whichever order the reader chooses, with neither presented as the ‘correct’ choice. In the the digital ARC I read, the first part is the fictional narrative, which concerns two friends - Marie and Edie - who meet at the former’s flat in the wake of their respective painful breakups (Marie with her ex-wife K, with whom she co-parented two children; Edie from an abusive partner), both choosing to ignore the blood seeping through Marie’s neighbour’s door.

Question 7 is a very difficult book to sum up. In simple terms, it’s a memoir, allowing Flanagan to dig deeper into themes he has explored in some of his novels, such as his relationship with his father (whose experiences on the Burmese Death Railway in WW2 were fictionalised as part of The Narrow Road…) and a near-death experience while kayaking as a young man (which informed his debut). But it’s also much broader than that.
