/lit/ - Literature

So I just finished Worm and, fuck man. I really, really hope my ending doesn't come off as as much of an asspull as what I just read.
>whoopsie a literal god forgets about its own powers and makes dumb mistakes
>also lol even though we've established concrete limitations for powers we're just going to break them at the last second to win
>oh yeah also, no real resolution to the main character plot/development lol, two bullets to the head should suffice right?
I mean come on, I wasn't exactly expecting perfection but I was at least hoping for something better than the average manga conclusion.

Are there any resources for how to write a synopsis? I can't fucking do it to save my life and looking at what I've written makes me cringe.
