Sinews of Heaven by Zanne Findlay

As a young girl, Isabella is suddenly faced with the loss of her twin brother in a tragic accident of misadventure. This uplifting tale follows her progress, coming to terms with his loss, and her journeys into a spiritual realm - an experience that goes way beyond her expectations and merely an imaginative way of keeping his memory alive. Initially her sojourns provide a place of escape, peace and solitude, but as she explores it opens out into a garden and a big house with magnificent rooms and people who open up a glimpse into a greater and more exotic meaning for life. It gradually becomes her foundation and begins to define her very existence, but at the same time giving her the confidence and strength to cope with real life.
