As many A Court of Thorns and Roses fans know, the original covers are widely loved and gorgeous. Our only problem- Bloomsbury changed the covers before A Court of Silver Flames was released. So, we have the first four books in the original covers, but A Court of Silver Flames in the new cover. Because of that, our sets are mismatched. Recently, a picture of the Russian version of A Court of Silver Flames popped up, and it’s in the same style as the original covers. So, this petition has started. 
So, here’s a petition for Bloomsbury to print ACOSF in the original cover. Penguin did it with An Ember in the Ashes, you can do it with ACOSF.
