Similar to this question, but more specifically about outright lies.
I am thinking of having a title that misleads or lies about the end of the novel. Something along the lines of “They Don’t Get Together in The End” so that the reader knows not to expect a typical boy meets girl story. The lie is that they DO get together, but just not in the way you’d expect (they are both asexual and end up in a vaguely romantic, nonsexual sort of partnership).
I don’t have any examples from books at hand, but in the film adaptation of Me and Earl and the Dying Girl
the narrator Greg directly assures the reader that Rachel is NOT going to die. As far as I remember he says it a couple of times. But then she does. I figure that the purpose of this was to recreate in the reader Greg’s disbelief that Rachel was ever really going to die. It’s also possibly making the point that our deceased love ones live on in our memories, or something to that effect.
I’m not sure the above example does it well, but needless to say this is difficult to pull off without pissing off your audience. So what could you do in order to make the lie easier to accept by the audience?
