Was the story interesting? Sure. It was all right. Books one and two were good, but this one? A bunch of long winded nonsense. Mostly, he just needed and editor. 600 page book could have easily been half that. Did I need 100 pages on the backstory of Zero?? No. Not even a little. It was meant to show the origin of the virus but the reality is it did nothing to further be plot and it was boring af. Add to that the random fancy words littered throughout the book (this was NOT a fancy book, the vocabulary was unnecessary and pulled me out of the story several times) and it just was not something I’d ever recommend.
