'A Darker Shade of Magic' by V.E. Schwab
The Plot: Imagine four parallel Londons, all with different levels of magic and monarchies. In Grey London, magic is supposedly a myth (like in our world); in Red London, magic thrives; in White London, magic is used by a ruling class against the population; and in Black London, magic corrupted and destroyed the world. It's "'Jonathan Strange and Mr. Norrell' meets 'Game of Thrones,'" Schawb said.
Gerard Butler's production company, G-BASE, has optioned the rights for a limited television series, with Schwab attached to write the pilot.
