Not yet released, but it looks very promising. The Sparks Fly Upward is a kind of sequel to the Makepeace Burke novels, about her daughter Philippa. The cover blurb:

A new novel of love and courage in a time of war, from the author of A Catch of Consequence and Taking Liberties.

Few of those Philippa loves in London return her affection. Not the love of her life, who has a new bride. Not even her widowed mother, Makepeace Burke. So Philippa decides on a marriage of convenience to a prudish, if kind, man.

Across the Channel in France, the Reign of Terror is causing the beheading of thousands from the French nobility. Among those in danger is Philippa's friend, the Marquis de Condorcet. Not only has Philippa the means of rescuing him from the guillotine, she's got the courage. And as fate would have it, Philippa will find love where she least expects it-while staring death in the face.

Scheduled for release on September 5.
