Of course, you already read The Rejectionist. But on the slight chance you missed the post with the Epic Gchat concerning books like The Secret History, I am directing your attention to it. Is it full of spoilers? Why, yes. If you have not yet read TSH, read it anyway.
By now, I expect -- as inevitably happens, even when I casually drop mention of TSH -- that people will come out of the woodwork to say things like "OMG, TSH, DO YOU KNOW HOW MUCH THAT BOOK FUCKED ME UP." They usually love it more than I do. Here is my emotional process upon finishing said book:
Me: *slaps book down* *makes noises of disgust* *goes off to write angry email to person who recommended book and sent a copy of it for one to read*
Me, two days later: *grumbles* That fucking book.
Me, two weeks later: JFC. THAT BOOK HAS FUCKED ME UP. *grudging admiration*
And now, two years on, can I say how utterly profound and fucked up this book is? I'm not sure I'm ready for a re-read. It is that wrenching of a read. But it sits in a place of honor -- er, top shelf of one of the many book cases in the house -- and I do heartily, verily believe that everyone should read it. But goeth thou and read Le R's literary chat with Cherie first. Because it shall certainly make one want to read TSH more than this post.
Also, stock up on the gin and tonic and limes. Good sipping while reading TSH.
