Like, one of the biggest differences between the All for the Game and this series (only comparing because people say they are alike), is that in All for the Game the books always end on a hopeful note with a monologue that is kind and reassuring and allows you to breathe until the next book and then there is Maggie fucking cliffhanger Stiefvater. 
 Also I wouldn't say that these series are very similar technically speaking but they make me giddy and excited in the same self destroying way that I love.
