I'm incredibly conflicted about this book. Perec's refusal to use the letter E is undoubtedly skilful in its execution, and to make the obvious void part of the story is genius! However, the absence of E is something that you will keep checking for throughout the novel to ensure you haven't been tricked - this will mess with your neurology as you process the storey. Paired with a meandering storyline (parts of which I am sure are unnecessary except to extend the novel in an act of excessive E-less grandstanding), this read can be a bit of a headache. 

Worth a read for those interested in the limits of language, or anyone seeking the occasional Wes Anderson-esque line amid avant-garde literary chaos.
