The 22nd of February is celebrated as 'World Thinking Day' by Girl Guides and Scouts around the world.
So to mark it why not read 'How the Girl Guides Won the War' by Janie Hampton. Talking about the work of the Girl Guide Association during World War 2 it's an interesting look at what girls aged 7 up did to support the war effort - from collecting thread spools (to be used to hide maps for prisoners of war) to raising money to teaching evacuees.
The book also looks at what was happening to Guides outside the UK in occupied Europe. Plus what happened after the war when the Guide Association sent members 18years and older to help with those being released from concentration camps etc.
Well worth a read, it shows not only what a amazing movement the Guide Association is but also just how much children and teenagers can do when challenged.
