"Some choices are unforgivable."

Widow, former hermit, and mechanical insect expert Dame Millie Day-Butterfield is newly knighted and newly wed. She struggles to move on after the devastating Tower of London battle to save Great Britain, but with faces from the past revisiting her, whom can she trust?

In the midst of a looming ban on alchemy that will affect the Butterfields' classified investigations into otherworldly aetherial devices, Millie's irritating cousin Eliza comes to visit and seems intent upon staying forever. The secret of the battle comes to light, and soon Millie is forced to face the unexpected consequences of her desperate actions. To her horror, she finds the past repeating itself and may once again be forced to take to the skies in another rescue mission. But who will cause the greatest betrayal of all?

Only months after overcoming her isolation and coming to terms with her first husband's death, Millie's new life begins to fall apart, and she may lose everything.

Pirate Widows of London is the sequel to the award winning steampunk novella, Keeper of the Mechanical Insects.
