@RavensDarkness write down the bits you have then as you do the rest might fall into place.
Or even write the next chapter and similarly you might get inspiration. It's worked for me in the past.
someday soon I'm gonna take down tragedy befallen books 1&2 to rewrite them and it may take a while so be patient. I don't really like the way its written. its one of the first books I wrote so it isn't that good. thnx!
