What an absolute joy of a read.
Written from the perspective of a cockroach, Archy, who relays the stories a cat named Mehitabel tells him.
Written without punctuation (because the cockroach can't reach the shift key on the typewriter), the writing is more like free verse poetry than it is prose. But it's so nicely written and has a nice warm rhythm to it.
It doesn't take itself too seriously at all and the sardonic sense of humour feels very modern despite the book being nearly 100 years old.
Another one of those books I'd recommend reading in one sitting cause of how short and sweet it is.
