I've really enjoyed all of the Andrew O'Hagan books that I've read, but this is quite a departure from the others. It's more ambitious in structure, and more powerful emotionally, which is not to say the others haven't been powerful, just that this novel carries quite a punch. There are two overlapping stories here. Anna Quirk, elderly and in the early stages of dementia, was once a pioneer of British documentary photography. Her grandson Luke is serving in Afghanistan where something terrible happens, which causes him to return to Scotland.
