A Darker Shade of Magic by V.E. Schwab takes us to a London where magic exists and those in possession of it can travel between alternate worlds. After Black London, filled with unquenchable and evil power, became a threat to the others, the doors were shut down to all except the Antari, a nearly extinct race of people who still have the ability to make these doors. To do so, they must use blood and a piece of the other worlds, which is only impossible for Black London, where no trace exists in the others any longer… or so we believe. The story has us follow Kell, an Antari from the lush and magically blessed Red London and Lila, a supposedly human girl with a penchant for trouble from the lacking Grey London, as they try to escape the power hungry White London’s rulers and return a powerful talisman to Black London.
