Travel-writer, novelist and singer-songwriter Malachy Tallack has been passionate about fishing since he was young. Growing up in Shetland, with its myriad lochs, he and his brother would roam the island in search of trout, and in so doing discovered a sense of freedom, of wonder, and an abiding passion. But why is it that catching a fish - or simply contemplating catching a fish - can be so thrilling, so captivating? Why is it that time spent beside water can be imprinted so sharply in the memory? Why is it that what seems such a simple act - that of casting a line and hoping - can feel so rich in mystery? 'Illuminated by Water' is Malachy's personal attempt to understand that freedom, and to trace the origins and sources of that sense of wonder.
