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.
