OK, so I am new to creative writing, but I have written a large portion of a novel set during WWII. It follows the story of six different soldiers (one German, one Japanese, one Italian, one Russian, one British and one American) and how their fates are entangled. I'm writing the story in six acts, each one following the tale of a different soldier. Throughtout the novel I explain how the Axis soldiers are just men fighting for their country like the allies, and how they are just as valiant and righteous. However, I also want to write a satisfying conclusion to the book, but I am unsure of how to tie up all of the endings. Any ideas?
