Chloe is enjoying activity camp and all the outdoor fun - what's not to like? But she can't understand why everyone goes on and on about "leaving things the way you found them". After all, what's the big deal about a bit of litter in the middle of the woods? The world is big enough for a bit of rubbish not to matter. But when she's given a mysterious compass with a fifth direction she's transported to a tropical island beach and has to brave the extreme conditions with the help of survival expert Bear Grylls. It's not like a typical trip to the seaside! First there's a shipwreck to escape through raging surf, fresh water to source, not to mention quicksand and sea urchins... Will Bear persuade her to change her ways when she sees how much non-degradable litter still washes up, and the damage it does to wildlife? And who will get the compass next?
