The Dark Days Pact (Lady Helen, #2)

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.
