Firstly, I have to own up to really liking Marian Keyes books. I think I have enjoyed all of them. If you are of the same mind, I really don't think this book is going to disappoint.
We revisit the Walsh family. As families go, they are probably a bit more screwed up and unusual than most but Ms Keyes never strays beyond the believable. This time it's the turn of Helen, the youngest. Helen has suffered a severe bout of depression in the past and is well on her way - terrified - into a new bout. In most cases, that would suggest a book that was heavy and gloomy. Yet, as always, Ms Keyes manages to combine a realistic and sensitive understanding of emotional problems with a book which is often laugh-out-loud funny and always quite gripping. I never felt dragged down by it, even while I could empathise with Helen's dread and fear. In any event, the descent into depression is interwoven into the main story, a missing persons case, in a way that doesn't detract from the mystery/thriller feel to this main story. Nor are her personal relationships neglected. You live Helen's life with her and it is a well-rounded and complete-feeling book and in that sense is very satisfying - no part is left sketchy and incomplete.
