Regency Imposters Books in Order

The Regency Imposters books are linked less by one location than by a shared interest in performance. These characters are pretending, hiding, withholding, or trying out versions of themselves that fit badly. Cat Sebastian uses that setup to ask who gets to belong, and what happens when love arrives before the truth is fully on the table.

Identity is the real plot engine.

Unmasked by the Marquess begins with Charity Church living as Robert Selby while helping her employer's sister chase a good marriage. What starts as disguise comedy quickly turns into something more searching, because the book cares about gender, social role, and the relief of being seen clearly. The romance with Alistair, Marquess of Pembroke, works because both characters are forced to rethink what they thought a respectable life should look like.

A Duke in Disguise shifts toward friendship, radical politics, and class. Verity Plum is trying to keep her publishing business afloat while Ash, her closest friend, learns that he may be heir to a dukedom. The book balances longing with a genuine interest in bookselling, pamphlets, money, and how power moves through Regency society.

A Delicate Deception slows things down in the Derbyshire countryside. Amelia Allenby wants solitude. Sydney Goddard arrives carrying secrets of his own. Their story is quieter than the first two, but it keeps the same series concerns: the gap between appearance and reality, the weight of family history, and the wish to make a life that feels chosen rather than assigned.

Together, the books make a loose, humane series about people refusing narrow roles. The tone ranges from playful to introspective, and the romances cross gender and sexuality in ways that feel natural to Sebastian's work. If you like Regency settings but want more class friction, more questions about identity, and more room for unconventional futures, this is a strong place to start.
