"Tell Me About" has been a hugely successful series which mixes clear and simple text with a superb array of photographs telling the life stories of inspiring and important figures from all areas of endeavour.

Sojourner Truth was a black woman whose parents had been captured in Africa and sold as slaves in America.

Sojourner was a slave until she was thirty, but when she won her freedom she dedicated the rest of her life to speaking against slavery, racism and inequality.

The carefully worded text and the superb array of illustrations are pitched at just the right level for young children finding out about the past.
