Dolphin Island is one of those solid, worthy Arthur C. Clarke books that has been out of print for many years and is now quite hard to find. This is a novel that Clarke wrote in the early 60's after spending a substantial amount of time around Australia's Great Barrier Reef. Clarke, as many are not aware, was, at least at one time, just as interested in diving and the sea as he was in space. Clearly fascinated by what he saw in his time around the reef, it inspired Clarke to write this novel, one of his very few targeted at young adults. As such, it lacks the poetic prose and philosophical and theological aspects that permeate Clarke's best novels. However, it is a very tight, well-written, and highly-enjoyable adventure romp. It is a very fast read, and you will be interested all the way through. Although it was intended as a book for young adults, Clarke being Clarke, this book is nevertheless packed full of interesting ideas and concepts. Clarke's speculations on dolphin intelligence and the many applications he dreams up for them are vivid and very believable. The descriptions of the Reef are also very poetic and sometimes beautifully rendered; however, as another reviewer pointed out, these sections tend to go on for too long and sometimes slow down the pace of the novel. Don't worry, though: it's nothing close to what he made it out to be. This is a very short novel to begin with, and these sections comprise the majority of only 3 or 4 chapters. Those more interested in the Reef and underwater exploration in general may find these sections more satisfying than I did. At any rate, this is a solid, action-packed adventure story that is a worthy read for any Clarke fan and recommended reading for younger science fiction lovers.
