It's in His Kiss

Hyacinth Bridgerton, the youngest and most outspoken of her siblings, discovers a hidden Italian diary at a house party. She convinces Gareth St. Clair to help her translate the text, as he is the grandson of the woman who wrote it. The two decipher a series of cryptic entries that suggest a cache of family jewels is hidden within the St. Clair estate. As they navigate Gareth’s hostile relationship with his father and track physical clues through the property, their partnership shifts from sleuthing to romance.

Readers who enjoy Regency historical fiction and the enemies-to-lovers trope find this story satisfying because of its focus on sharp dialogue and intellectual parity. It serves those looking for a mix of domestic mystery and romantic comedy. The audience walks away with a resolution to the central treasure hunt and a depiction of a marriage built on wit rather than social obligation. The book provides a detailed look at the social dynamics of the ton while resolving the overarching Bridgerton family narrative.
