Mangan has an MFA in fiction writing. I think she should ask for her money back.

In every area -style, plot, characterisation - the novel is either weak or derivative (mainly of The Talented Mr Ripley)

Here’s an example from where a character encounters someone smoking a cigarette. ...and I watched, fascinated as plumes of smoke enveloped her, spreading throughout our room, as if hungry to mark the corners of it, to claim it.

And that type of over-writing can be found on practically every page.
