What is your favourite book or book series? Why? My favorite books are a series called the Earth's Children series,& they're by Jean M.Auel.(The first book in the series is called 'Clan of the Cave Bear',then it's 'Valley of the Horses','The Mammoth Hunters','Plains of Passage','Shelters of Stone',& the final book in the series is 'The Land of Painted Caves'.I love those books;even though there's only 6 books in the series,she puts so much research into them that the first book came out in 1981,and the final book didn't come out until 2011. And romeo and juliet by william shakespeare The fifth book came out in 2002,so I was so excited when the 6th & final book came out because I had been waiting 9 years for it. They take place in ice age Europe during the late Pleistocene Era,which I've always been really fascinated with.
