The Unknown Identities series runs nine books following covert operatives whose real identities are classified. From Bulletproof and Double Vision through Moving Target and Mirage, each book pairs a different agent with a romantic interest while navigating missions that test both their skills and their hearts.
Published between 2013 and 2019, the series represents Black’s take on spy romance — characters who can’t reveal who they really are falling for people who make them want to.
