this bitch won't leave my mind even though it's been 1,5 years since i read it... it's very special, the hippie-era surrealist prose-poetry... there's nothing quite like it.

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. 

Based on the reviews I have seen, this is a love-it-or-hate-it book, and I really wish I found there to be any morsel of genius so that I could love it, but yiiiikes this is incredibly bizarre and incoherent. 
The first half is boring as hell, and the second half is a tonal rollercoaster. Reading this book feels how I imagine it would feel to be the only sober person with a group of strangers that you are somehow in charge of keeping alive, who are all on psychedelics, and then right when you think they are going to fall asleep they all start to bad trip and scream. 
Honestly I just saved you the trouble of reading the book, but if that strikes your fancy, have at it.
