If there is one thing that makes a great book even better, it is when it has a cover that we love! The cover design is what catches the eye as we browse through a bookstore shelf or check out the Amazon or Goodreads recommendations. The right cover makes me look closer at a book, to read the blurb and maybe make a purchase. A poor cover might mean I never look at the blurb at all.
I haven't read anything of Sarah J Maas despite people raving about it but then I don't read much fantasy. I do however, love fantasy book covers and the first books in this series are pretty!
Then we seem to move to new covers...maybe a change of character or something. I still like it though not as much as the others, but it doesn't of course match the first five.
