After the Iron Duke freed England from Horde control, he instantly became a national hero. Now Rhys Trahaearn has built a merchant empire on the power — and fear — of his name. When a dead body is dropped from an airship onto his doorstep, Detective Inspector Mina Wentworth is drawn into his dangerous world — and he intends to make her his next possession.
But when Mina uncovers the victim's identity, she stumbles upon a conspiracy that threatens the lives of everyone in England. To save them, Mina and Rhys must race across zombie-infested wastelands and treacherous oceans — and Mina discovers the danger is not only to her countrymen, as she finds herself tempted to give up everything to the Iron Duke.
