I started working on the first draft on the second book in my trilogy. I've written around 19k words for it, but now I'm thinking about scraping it because what is the point of keeping it if the plot doesn't line up? I plotted everything for this draft too so feel like I did all of that for nothing.

Unless if I keep it and use it as a way to help me come up with ideas for the actual final draft of the second book!

Send your advice if you have any! I need it!
