As a grandmother of grandsons I read this book to see if it would be suitable as a stocking stuffer or birthday present. It most certainly is, for kids who are dinosaur mad. (And which kid of a certain age isn't!) I hadn't realised that there were dinosaurs in Antarctica back in the day when it was a temperate, forested Gondwana. And that some of them left their bones behind (how careless). The story tells of how the young boy Josh and his father Steve are part of a team of scientists out to retrieve such a bone - and of all the challenges and adventures they encounter, from vicious storms to a recalcitrant bone. The book is certainly a page turner, but it's also the story of how Josh and his father learn to appreciate one another anew as they participate together in dealing with those challenges. And then at the end of the book - what a climax! and the epilogue is a marvellously inventive way of concluding the story. Thoroughly recommended for youngsters.
