Bridget MacCaskill has been observing otters for many years and studies undertaken with her late husband Don resulted in books and a film about otters and their environment. Otters are fascinating and delightful creatures but to watch them in their natural habitat requires immense patience over a long period of time and an appreciation of their way of life. For those of us who wish to know more, this book presents an intimate account of an extended otter family. It is written in the form of a story by an unseen observer and tells of the lives of two otter cubs from birth until adulthood, their relationship with their parents and the other otter family on the loch, and their interaction with some of the other creatures there. Enter Coll and Coire, Kyle and Kelpie. All the events in this book are based on actual observation, either from watching the animals themselves or by interpreting signs of their presence. The result is a book that is true to nature and not in the least sentimental. But it conveys a serious message - we must be aware of the need to minimize pollution, disruption of habitat and other harmful intrusions if we are to benefit from the presence of these wonderful creatures. The book should appeal to everyone with an interest in otters and all lovers of wildlife and the natural landscape.
