So hard to choose any one book as a favourite, or even just one author. I love everything from the 18th-19th century classics, to modern novels - Dickens to J.K.Rowling. I've just started to re-read the 6-book 'Earth's Children' series by J.M.Auel; 'Clan of the Cave Bear' is the first book in the series, and begins the tale of a time towards the end of the last Ice Age, when modern humans and Neanderthals shared Europe with the Ice Age animals - a very well researched and creative series, that gets you thinking about human origins, human advancement, belief systems, customs etc. I loved Enid Blyton as a kid and one day hope to re-read some of my favourite childhood stories.
