Hi Suzi, I have to admit to being a bit puzzled by this one also. I really enjoyed her two earlier books: 'She's Not There' and 'I've Just Seen a Face'. As a result, I was excited about 'Stuck' but...
Two things have crossed my mind about this. First, perhaps Zoe is accurate in suggesting the point may be the universality of the parenting experience. At some level, anyways, it doesn't matter if you are X, Y, or Z - being a parent is being a parent. Second, I wondered if perhaps Boylan has reached the end of the thread that started with 'Not There'. The string, as they say, has run out.
All this considered, though, she's got an engaging writing style and, taken chapter by chapter, bit by bit, her tales are always enjoyable journeys.
