Bridgerton Tome 7
It's In His Kiss

Fiendishly smart, devilishly outspoken and - according to some, particularly one Gareth St Clair - probably best in small doses. But there's something about her, something charming and vexing, that grabs one and won't quite let go. Gareth and Hyacinth cross paths at the annual - and annually discordant - Smythe-Smith musicale. To Hyacinth, Gareth's every word seems a dare, and she offers to help him out with a knotty inheritance problem he's facing.
However, as they delve into the mysterious St Clair history, they discover that the answers they seek lie not in the past, but in each other, and that there is nothing as simple, or as complicated, as a single, perfect kiss.
