Which book covers are particularly beautiful?

"White Night Journey" by Higashino Keigo, there is a large blank space, two children holding hands, the shadows are so long, there are only two of them in the huge space, isn't this what is explained in the book, They are each other's sun, but they peel off the cocoon, and in the end there is a conspiracy behind the tenderness. The style of a book can be seen from its cover, and "White Night Walk" appropriately embodies this tone.
