Witness the fate of beloved heroes - and enemies. THE BALANCE OF POWER HAS FINALLY TIPPED... The precarious equilibrium among four Londons has reached its breaking point. Once brimming with the red vivacity of magic, darkness casts a shadow over the Maresh Empire, leaving a space for another London to rise. WHO WILL CRUMBLE? Kell - once assumed to be the last surviving Antari - begins to waver under the pressure of competing loyalties. And in the wake of tragedy, can Arnes survive? WHO WILL RISE? Lila Bard, once a commonplace - but never common - thief, has survived and flourished through a series of magical trials. But now she must learn to control the magic, before it bleeds her dry. Meanwhile, the disgraced Captain Alucard Emery of the Night Spire collects his crew, attempting a race against time to acquire the impossible. WHO WILL TAKE CONTROL? And an ancient enemy returns to claim a crown while a fallen hero tries to save a world in decay.

It has been four months since a mysterious obsidian stone fell into Kell's possession. Four months since his path crossed with Delilah Bard. Four months since Prince Rhy was wounded, and since the nefarious Dane twins of White London fell, and four months since the stone was cast with Holland's dying body through the rift--back into Black London. Now, restless after having given up his smuggling habit, Kell is visited by dreams of ominous magical events, waking only to think of Lila, who disappeared from the docks as she always meant to do. As Red London finalizes preparations for the Element Games--an extravagant international competition of magic meant to entertain and keep healthy the ties between neighboring countries--a certain pirate ship draws closer, carrying old friends back into port. And while Red London is caught up in the pageantry and thrills of the Games, another London is coming back to life. After all, a shadow that was gone in the night will reappear in the morning. But the balance of magic is ever perilous, and for one city to flourish, another London must fall.
