How did you manage to put all the ideas you had in your head down to form a complete book ? I have the hardest time trying to figure out a way too end it or the point I'm trying to make with my book :/

I try to live by a simple phrase: You can always edit a bad page, but you can’t edit a blank page. Because you’re absolutely right — it is crazy hard to end books, and figure out the points you’re trying to make, and pretty much write in general. Pressing on to finish the first draft should be Priority #1.

But how to even get to the end of a book? I always like to come up with the final sentence, so I know where I need to end up. It doesn’t even have to be the full final scene (and this final sentence can change through drafts) — just one line so I know “This is my destination.” It helps having some small focal point around which you can craft your first draft, so there’s a general forward flow. 

As for finding out the point you’re trying to make: the overall theme of the whole SNOW LIKE ASHES trilogy is a rather huge spoiler, but it came from something personal to me that I wanted to pass on to readers. That’s where most of the themes of my books come from: personal experiences/lessons/beliefs I want to portray through story. Oftentimes, these themes develop organically in the story. When I started writing SLA, I didn’t necessarily intend for it to end with the theme it did. Stories take on lives of their own in rather wondrous ways!

I hope this helps! There are endless pieces of advice regarding writing, so if you find one that doesn’t sit well with you, or isn’t something you feel works for you, plunge ahead to something new. There’s no right or wrong way to do any of this — there is only your way!
