In the conclusion to the Threads of Magic trilogy, Charity and Bridgette vow to bring justice to their plague-ridden Victorian world that is ruled by corrupt Lords and dark magic wielding High Priests.

Still reeling from the loss of a loved one, Charity is running out of time to save the rest of her friends. She does something she thought she'd never do: ask her father for help.

Bridgette must heal her relationship with Rose and learn to control her burgeoning powers while Charity faces her ultimate challenge, healing a plague victim while under public scrutiny in the place Bridgette fears most.

Bridgette and Charity struggle to stay one step ahead of Lord Carolinus, to determine his plans for patients secretly transferred to a new medical clinic. The daughter holds hope that her father is not beyond redemption.

Let all of Albion know the truth, and let the plague be lifted. Before it's too late.

A Formidable Charity is the exciting finale of the gaslamp fantasy trilogy Threads of Magic by award winning author K. A. Quinn.
