London, April 1812. On the eve of eighteen-year-old Lady Helen Wrexhall’s presentation to the queen, one of her family’s housemaids disappears-and Helen is drawn into the shadows of Regency London. There, she meets Lord Carlston, one of the few who can stop the perpetrators: a cabal of demons infiltrating every level of society. Dare she ask for his help, when his reputation is almost as black as his lingering eyes? And will her intelligence and headstrong curiosity wind up leading them into a death trap?

This novella is from Lord Carlston’s perspective and starts at the point in The Dark Days Club when he and Lady Helen meet for the first time.

June 1812. Just weeks after her catastrophic coming-out ball, Lady Helen Wrexhall—now disowned by her uncle—is a full member of the demon-hunting Dark Days Club. Her mentor, Lord Carlston, has arranged for Helen to spend the summer season in Brighton so that he can train her new Reclaimer powers. However, the long-term effects of Carlston’s Reclaimer work have taken hold, and his sanity is beginning to slip. At the same time, Carlston’s Dark Days Club colleague and nemesis will stop at nothing to bring Helen over to his side—and the Duke of Selburn is determined to marry her. The stakes are even higher for Helen as she struggles to become the warrior that everyone expects her to be.

The thrilling, genre-bending conclusion to Lady Helen's demon-hunting adventures, set in the glittering Regency world. Lady Helen has retreated to a country estate outside Bath to prepare for her wedding to the Duke of Selburn, yet she knows she has unfinished business to complete. She and the dangerously charismatic Lord Carlston have learned they are a dyad, bonded in blood, and only they are strong enough to defeat the Grand Deceiver, who threatens to throw mankind into chaos. But the heinous death-soaked Ligatus Helen has absorbed is tearing a rift in her mind. Its power, if unleashed, will annihilate both Helen and Carlston unless they can find a way to harness its ghastly force and defeat their enemy. In the final book of the trilogy that began with THE DARK DAYS CLUB and continued with THE DARK DAYS PACT, the intrepid Lady Helen's story hurtles to a shocking conclusion full of action, heartbreak, and betrayal.
