Clues . . .
It's more than a cover. It's a book cover of a book cover with a portal to another world.
Many of its images refer to important symbols in the story. A broken snowflake pendant . . . a glittering white butterfly . . . the book itself . . . and its revealing window with the glowing dwarf evergreen and purple door. Where does it lead? Did you notice the freaky horse in the upper right corner? It's from a famous painting*—and one of the story's more "charming" characters.
How are they all connected?
