I want to know if this sentence is correct:

Already at the beginning of the book there is a complication in the story.

Can the word complication be used here? It sounds a little unusual to me, so I want to check this with others. It means that already at the beginning of the book things started happening and there was a turn in the story (although I'm not quite sure that turn can be used here). My dictionary says that it's also possible to say "the plot thickens", but unfortunately I need a noun here. Which would be the best word, is complication o.k. after all?
Yes, 'complication' is fine, Lana. Alternatives might be 'an unusual twist in', 'an unexpected turn to' the story.
ok, thx.
