This is Alice in Wonderland the free audio book by Oxford mathematician and children's story teller Lewis Carroll.

Following a picnic along the Thames, Charles Dodgson began telling the story of Alice and her adventures down the rabbit-hole. An idea that he said was an attempt to,

 "strike out some new line of fairy-lore".

He goes on to describe Alice and her travails as she meets and struggles with the logic of the hookah smoking caterpillar, the cheshire cat, the mad hatter plus many more characters that have become synomous with Carroll and the best of children's literature.
