Have to admit, I was so bored with this I did not end up finishing the book.
This is a surreal fantasy based around a single character, whose main identifier is that he is a depressed writer.
The start of the book I found particularly challenging, not just because the early chapters describe dreamlike surreal sequences, but largely because of the language used.
The prose is heavily descriptive and displays an almost ostentatious use of English vocabulary, to the point that some sentences become (unintentionally) amusing to read; the author seems to be trying a little too hard to impress.
It took several chapters to fathom any kind of insight into what was going on, and at no point was I entertained in the slightest.
This might hit the right nerve for readers that are themselves depressed, or have been, but otherwise I can only recommend to those who enjoy the idea of a surreal, abstract English lesson.
