If an acid trip was a book it would be this. Yes I say that having never been on acid. Whatever. In Watermelon Sugar is set in a post-apocalyptic utopia where the sun shines a different colour every day, and where everything is made of “watermelon sugar”.  It follows a nameless narrator as he runs through events which take place surrounding the commune he lives on - iDeath. This book is less about character development and more allegorical I’d say; as a reader you’re quite distant and alienated from the characters and the focus isn’t on development. In fact at times the characters motivations are so difficult to decipher that you wonder if it’s the books fault rather than your own. 
Brautigan’s writing style is strange at first but you get used to it. It’s very minimal - pretty much comprising entirely of simple and compound sentences. I loved the concept of this book- Brautigan wrote in the context of the counter cultural movements of the 1960s- about the limitations of idealism, which is something worth pondering even today. It’s also the name of a Harry Styles song.
