Very few women think they have the 'perfect' 21st-century family, and Samantha Smythe is no exception. Most of the time, she takes that in her stride - unfazed by the amount of time Edward, 8, spends drawing pictures on his willy, Bennie, 2, avoiding a potty and a baby Jamie refusing to eat anything but butternut squash. Samantha and her husband, John, are holding it together and embracing the chaos. But sometimes she does wonder: is it possible, when your first son's father is entirely absent, and you are now the mother of two more boys by your second husband, to have a real family? The one you always dreamed you'd have?
And then the absent ex-husband makes a dramatic reappearance and somehow ends up borrowing the spare room. This, of course, is enough to throw the family dynamic entirely off-course. With sanity and capacity for rational thought in short supply, can Samantha protect everything she holds dear, without disappearing out of sight herself...?
