The View on the Way Down by Rebecca Wait.
This is one of those novels that begins quietly, with just a hint of what is to come. We are introduced to a "normal" family - mum, dad, two sons and a daughter. As the tragic story reveals itself, we can see how this family is struggling to come to terms with the awful tragedy that affects them all. They are dysfunctional at a deep level, made all the more dysfunctional by the veneer of normality that the mother in particular tries to project. I won't go in to too much detail about the plot, as this is one of those stories that needs to be read with uncluttered eyes, but I think by the end you will be weeping like I was. Along the way there are flashes of humour too, and it's not at all gloom and doom; it is incredibly uplifting and moving with a happy-ish ending. Do read it, it's a wonderful novel.
