There were once four worlds, each pulsing with fantastical power and connected by a single city: London. Until the magic grew too fast and forced the worlds to seal the doors between them in a desperate gamble to protect their own. Now, only three Antari are known in recent memory --- Kell Maresh of Red London, Delilah Bard of Grey London, and Holland Vosijk of White London. But barely a glimpse of them have been seen in the last seven years --- and a new Antari named Kosika has appeared in White London, taking the throne in Holland's absence. The young queen is willing to feed her city with blood, including her own --- but her growing religious fervor has the potential to drown it instead. And back in Red London, King Rhy Maresh is threatened by a rising rebellion.

Kell is one of the last Antari --- magicians with a rare, coveted ability to travel between parallel Londons. Kell was raised in Arnes --- Red London --- and officially serves the Maresh Empire as an ambassador, traveling between the frequent bloody regime changes in White London and the court of George III in the dullest of Londons, the one without any magic left to see. Unofficially, Kell is a smuggler, servicing people willing to pay for even the smallest glimpses of a world they'll never see. It's a defiant hobby with dangerous consequences, which Kell is now seeing firsthand. After an exchange goes awry, Kell escapes to Grey London and runs into Delilah Bard, a cut-purse with lofty aspirations. She first robs him, then saves him from a deadly enemy, and finally forces him to spirit her to another world for a proper adventure.

France, 1714. In a moment of desperation, a young woman makes a Faustian bargain to live forever --- and is cursed to be forgotten by everyone she meets. Thus begins the extraordinary life of Addie LaRue, and a dazzling adventure that will play out across centuries and continents, across history and art, as a young woman learns how far she will go to leave her mark on the world. But everything changes when, after nearly 300 years, Addie stumbles across a young man in a hidden bookstore and he remembers her name.
