Rainbow Recs #1 - Red

Welcome to my newest obsession and that is sorting books by the color of their covers 😍 What this means is that, from time to time, I'll give you book recs based on the colors of the rainbow. Of course, we are starting with red 😊 All the covers are linked to the GR pages of books and these lists will include sequels as well, because they deserve recognition too and because it's not easy to come up with so many books without including them 😂

   

Two of these are mystery novels and two are fantasy. Two are beginnings, two are sequels. All four were equally amazing 😍 Which red book would you recommend?
