A beautifully bizarre little book. It's a mixture of mathematics, philosophy, and commentary on social society (classism and sexism) all whilst telling quite an engaging story about inter-dimensional travel through the 'eye' of Mr. A. Square. I found it hopeful and heartwarming as well as academically interesting. Its key message was to encourage people to imagine things beyond their immediate experience of the world.

Don't let the mathsy nature put you off. Abbott writes very clearly and describes complex geomtry by putting you in the position of the protagonist (the Square). It's genuinely interesting seeing things from his point of view. The progression of his story can nicely lead the reader to apply the same logic to their own experience living in three dimensions, and question the potential limitations of their experience. 

My favourite chapter was the one on the history of colour in Flatland. How it was used for practical and personal reasons, how it led to political and societal turmoil and rebellion and ultimately suppression. I think it is truly one of the best pieces of writing I've ever read, completely deserving of the term genius.
