Harriet and Khuwelsa are teenage sisters and they love flying over the grasslands in their flying machine: The Iron Pegasus. But East Africa is a cauldron of political tensions as the global empires of Britain and Germany vie for control.

When the sisters stumble into the middle of a German military build-up, they are taken prisoner to prevent them revealing the truth to the British. To prevent a war they must escape their captors and warn their father in Zanzibar - but even if they succeed who will believe a couple of teenage girls?

To stop the invasion they must put their own lives on the line against Zeppelins and war planes, in a completely unarmed vessel.

In the best traditions of derring-do these three non-stop Iron Pegasus stories (Harry Takes Off, Harry in the Wild and Harry Gets Her Wings) will keep you on the edge of your seat in a rollercoaster ride of Action and Adventure.
