Summer, 1812

After the scandalous events at her presentation ball in London, Lady Helen has taken refuge at the fashionable seaside resort of Brighton, where she is training to be a Reclaimer with the covert Dark Days Club.

As she struggles to put aside her genteel upbringing and take up the weapons of a warrior, Helen realizes that her mentor, Lord Carlston, is fighting his own inner battle. Has the foul Deceiver energy poisoned his soul, or is something else driving him towards violent bouts of madness? Either way, Helen is desperate to help the man with whom she shares a deep but forbidden connection.

When Mr Pike, the hard bureaucratic heart of the Dark Days Club, arrives in Brighton, no one is prepared for the ordinary evil he brings in his wake. He has a secret task for Helen and Mr Hammond, and the authority of the Prince Regent. They have no choice but to do as he orders, knowing that the mission will betray everyone around them and possibly bring about Lord Carlston's annihilation.
