The Lost King

Seventeen-year-old Nyx Madden has given up stealing shadows. This rare power, which allows her to control the person whose shadow she holds, has no place in her new life. Now, Nyx serves as the newly-crowned King Adrian's guard-an occupation that makes it easy for her and Adrian to slip away from their duties to enjoy each other's company whenever they please.

But Adrian's role as king is proving difficult. A new disease, the Red Plague, is spreading over Durnwall and leaving death in its wake. The Underworld, Itoria's most notorious criminal organization, is out of control and, somehow, orchestrating the spread of the plague. To make matters worse, the people of Itoria are searching for answers about the Shadow Thief, the secret identity that Nyx desperately wants to leave behind.

When Adrian suddenly vanishes after Luther, a man claiming to be his long-lost brother, arrives in Durnwall, Nyx must act. Accompanied by Grey, an old ally who once saved her life, Nyx searches for Adrian. Along the way, she discovers another side to the Shadow Thief-one that might be the key to saving Itoria from the threat of the Red Plague.
