Tomorrow War is another short book from J. L. Bourne, a military veteran with 22 years of service, but unlike Day by Day Armageddon there are no zombies this time around. In this story the zombies are replaced with something far scarier - other humans and a dysfunctional government. Keeping a similar journal format to the Day by Day series, the main character, Max [Redacted], writes down his experiences as a form of self therapy to help him cope with the things he decides that he must do to survive. Being a trained killer working for the US government before society goes to hell, Max conducts a covert mission that becomes the root cause of the financial collapse that ruins society. This guilt weighs heavily upon him after the fall as he struggles with both the threats of the new world and his own mental health.

This work originally started as an online journal where each entry was uploaded piece by piece and appeared as if it was hand written by the protagonist as he tried to survive a zombie apocalypse. It was published in this unconventional way because J. L Bourne wanted it to feel real and raw and was quoted as saying "there are no publishers or editors in the apocalypse." Eventually this unique work was compiled and morphed into book form but the journal entry format remained in tact which is a good thing since it happens to keep the story moving forward rapidly. Couple that with the credibility that Bourne's 22 years of military and intelligence service brings to his main character, who is also military, and you have a unique work worth experiencing within a very crowded genre.
