The third title in this unique series by global bestseller and science educator Lucy Hawking about a former princess desperate to find out about the world around her - and what she can do to help it. Illustrated throughout by Zoe Persico and with fascinating non-fiction sections from world-renowned scientists, this is perfect for readers 7 and over.

Olivia much prefers life as a scientist to life as a princess. And now she has to solve her biggest science mystery yet!

'We have done some investigations into the changes we see, feel and experience in the climate around us. You might not want to know about these changes, but you need to know about them because this is the world you're going to leave to us young people when we're adults!'

Olivia and her best friends, Ravi and Helga, aka The Climate Crew, start to realise that the problems in the environment around them are all connected to each other,
and all to do with the way the Earth is being looked after by everybody on it. They need to help.

When they realise that a group called the Knights of Nature, set up years and years ago, believe the same things they do and also want to help, they decide to work together.
Protecting Alez's weather and countryside and animals and people - and, well, everything, really! - awaits them.
