Okay how about this: There's this guy, let's call him "Baha", and this "Baha", he really has it in for this one particular er, shark, yeah, that's it - it's a shark. So this "Baha" sets sail to find this shark and kill it at any cost. Maybe you can use a third-person narrator, call him Isaiah or something like that. What do you think? Great stuff, right?
If you don't like that one, how about this: So there are these three brothers and they live somewhere in Russia, let's call them "The Brothers Kusnetsov", okay? So these three brothers, they're all very different in character and all of their lives have gone in different directions and the book can touch on the themes of family, free-will, mortality, Christianity, life and death and maybe poverty too.
Still not sold, okay here's another one for you: There's this guy, let's call him "Lambert-Lambert", anyway, he's a foreigner and an anarchist and a bit of a snob. Oh and also he's an odious pedophile but we'll get to that. Anyway, this Lambert-Lambert falls in love with a pre-pubescent girl named Tristressa. Lambert-Lambert marries her mother (whom he despises) and carries on a terribly awkward and incredibly immoral affair with the girl and in the process, ruins both her life and his own until he is driven to commit murder before finally dying of a broken heart (codenamed "coronary thrombosis") Pretty sweet, huh?
The point is, write your own books and make up your own stories.
