Jock and Lassie are West Highland Terriers who live with the author and her husband on Waiheke Island, which lies about twenty kilometres offshore from Auckland, New Zealand. The two dogs are brother and sister from the same litter. Lassie is usually the more cautious and wiser of the two, while Jock is rather reckless, typically getting himself into all sorts of scrapes. Of course, Jock rarely takes heed of his sister's warnings and lands himself in all sorts of bother. This book tells the story of their first journey to Waiheke on the car ferry, the sights they see along the way and Jock's misadventure when his curiosity about Waiheke's sea life gets the better of him!
