Eliza Broad has overcome trauma and loss to become the confident woman and spy she is today. Allen Strathem, fellow spy and good friend, has loved Eliza since the moment he first set eyes on her. But he left England without telling her so, bound for a mission on the Crimea with his secret buried deep.

When he returns, Eliza is tasked with helping Allen recover from the horrors he has experienced, and she dedicates herself to banishing the specters of his Russian captivity and restoring the sparkle in his eyes.

As Allen recuperates, they realize danger has followed him back to England. Together, they set a trap for the man who tortured him, only to discover something far more menacing afoot. With danger and intrigue around every corner, Eliza and Allen rely on and trust each other, and soon their once-buried love becomes a driving force. The perilous adventure they share and thrive on binds them together, but will that be enough to protect them from those who wish to see them dead?
