The daring and dramatic conclusion to Kat Dunn's epic C18th French Revolution trilogy 'with lashings of lust, love, sacrifice, betrayal and horror'.

Robespierre is dead. The Reign of Terror is over.

As Royalist strength grows, the Duc de L'Aubespine plots a coup that will consign the revolution to history. With Olympe in his clutches, he believes nothing can stop him. But he's reckoned without the intrepid Battalion of the Dead!

Reunited in Paris, Ada is poised for action – but if she plays her hand too soon, everything she's sacrificed to gain his trust will be lost. Meanwhile, an unlikely alliance with an old enemy might be Camille's only option to save Olympe and stop the duc in his tracks.

The glittering and macabre bals des victimes and the eerie catacombs make the perfect backdrop for the final episode of the Battalion's tale.
