Love the gentle humour. Joyce offering biscuits that were "own brand" but a Greg Wallace documentary had revealed they were made in the same factory as the expensive ones. The characters really come to life with their day to day preoccupations.
There's far too much head-hopping though, and sometimes it happens mid-chapter. A novel should have five POV, max, ideally more like three. We bounce from Donna, to Chris, to Ibrahim, Elizabeth, the bad guy, another bad guy, Joyce... This would have been a far stronger narrative had we stayed with Joyce.
