Three Body Problem was the original title for my novel, Before the Sun Hits.
Unfortunately, as we were editing and starting on the cover, another science fiction novel entitled The Three Body Problem by Liu Cixin was published, before I could get mine out.
I still like “Three Body Problem” because it refers to both literal and figurative themes central the story. However ultimately, Before the Sun Hits is a better title, I think, because it captures the essence of the novel.
Very few review drafts exist with the original title.
