Bought this for my 8 year old son who hates reading. Very much a modern day famous five. Interesting stuff, a few tricky words, plus details they can "google" to find out more - my son spent hours learning about komodo dragons. One of the kids on the desert island is diabetic so could be interesting for kids with the condition themselves, or to understand more about a family member's condition. Survival tips at the back of the book as well. First book in the series and I will be buying more for my son.
