The Countess Conspiracy

Sebastian Malheur is scandalous London's most infamous scientist-rake, but the groundbreaking theories that made his name are not his own. For years they have belonged to Violet Waterfield, the widowed Countess of Cambury, who works through him to keep her respectability intact.

When Sebastian threatens to end their long conspiracy, Violet must decide how far she will go to protect it, and what it might cost her to finally let him in — even if it means opening her guarded heart to the one man who could ruin her for good. The third full-length novel in Courtney Milan's Victorian-set Brothers Sinister series.
