A very easy, fast read, this book lives and breathes for its Ugandan character, Mary Tendo. Having lived and worked in London (and other cities and countries), she starts the novel back in Uganda, settled and in charge of a linen room in a hotel. A letter arrives, offering her a job if she returns to London, where the now-adult son of the woman whose cleaner/nanny she had been, many years earlier, has suffered a mental breakdown. She's asked to return, to help him heal.
Mary Tendo is the momentum and the heart and soul of this novel. The other characters are... dubious. Vanessa Henman, her employer, is reprehensible to the point of caricature. Hypocritical, self-absorbed, egocentric, racist, controlling, arrogant, bitter and petty with a self-image that is self-sacrificing, equanimous, tolerant, generous... basically, a vile person who thinks very highly of herself. Her son is a messed up crybaby who love-hates his mother, and the way his breakdown is portrayed feels about as inauthentic as it could possibly be. He is portrayed as so dysfunctional that it is not credible he could ever have been functional. The ex-husband is Mr Nice, the creative writing students are screaming cliches... basically, aside from Mary Tendo, all characters are cardboard, and none of them convincing.
It is a little odd, like reading an animated movie with one human character in it (like Space Jam or Song of the South), where the one human character is a Ugandan black woman, and she's stuck in a posh cartoon Britain.
The story tries to preserve its universality by only naming big things: London, Uganda, Kampala. Mary and Vanessa both hail from villages, which remain unnamed, sketched in only the vaguest terms (leading to a weird awkwardness when Vanessa's home village is visited, and it keeps being referred to as 'the village' while all the big cities were named). There are mobile phones in the book, but other than that it seems to have been written out of time - is it set in the 1990s, 2000s? People write letters; there appears to be no internet, or it is unimportant and no part of people's lives. Maybe the book is set in the second half of the 1990s, when laptops and mobiles co-existed without the web being the be-all and end-all of communications.
Sometimes, the book does not quite follow its own logic: someone working hard and saving up £3000 for lots of blood, sweat and tears is unlikely to let her boyfriend fly over from Uganda (which presumably would cost £600-800 or so).
The book also seems oddly inconsistent: sometimes it's told in third person, close to either Mary or Vanessa. Sometimes it's in first person. Some scenes drift close to one viewpoint character after another.
Basically, this is a book with a colourful, three dimensional main character, stuck in a two-dimensional world with clunky writery craftsmanship around the edges.
It's brisk and entertaining, but not terribly rewarding or enjoyable to read. (The British characters sap all the joy from it...)
