Who wrote the novel Tomorrow to educate public about horrors of American war?

There is no widely known novel called "Tomorrow" that specifically aimed to educate the public about the horrors of the American war.

It's possible you are thinking of a different novel.

To help me find the book you're looking for, could you provide more information?
