Book excerpt: Did you know that there are more than twenty-one rivers in London? Many of them have been forced underground by the development of the city but they all have their own history and their own stories to tell, from Roman times to the present day. Anne and Sef have dredged these tales from the silt, bringing them to the surface for you to enjoy. Tales of mudlarks and refugees; a pirate queen and Vikings; a young boy running away from enslavement, and many more all flow through the pages of this collection. Seas and oceans have been crossed, dangers overcome, and these ancestors of ours come to life as they tell their stories once more.
