All together the series is 4 books long, each one follows a horseman of the apocalypse who has come to earth to destroy it because humanity has become wicked and it is their divine mission to kill everyone, you know, how they do. Honestly this whole series vividly reminds me of something I would have read from ages like 13-16 in the best possible way just with some sex. The relationships are toxic, the women manic pixie girls each special in their own way, and only the magic of their undying true love will save humanity, I delighted in it. Sometimes you just need the experience of reading Twilight without the love triangle or Mormonism and that is what these books are. Are they good, not really, did I tear through them in as few sittings as possible, you bet I did.
