The Rousseaus Books in Order

The Rousseaus is the third branch of Katy Regnery's Blueberry Lane romance world. These books follow the Rousseau siblings as their sophisticated Philadelphia lives become tangled with old feelings, family history, and people they did not expect to need.

Jonquils for Jax follows Jacqueline "Jax" Rousseau, a wealthy, lively woman who meets Gardner Thibodeaux, a landscaper who is not impressed by her charm or her assumptions. Their difficult first impression becomes the starting point for a romance that asks both characters to look past appearances.

Marry Me Mad centers on Jax's twin, Madeleine "Mad" Rousseau, and Cortlandt Ambler. Their story is rooted in a long connection and the question of whether people who have loved each other quietly for years can finally be honest about it.

The final book, J.C. and the Bijoux Jolis, follows Jean-Christian Rousseau and gallery owner Libitz Feingold. A found portrait sends them on a search that reaches from Philadelphia to New York and Marseille, giving their enemies-to-lovers connection a mystery to work through.

The books belong to the wider Blueberry Lane setting, with familiar families appearing around the edges. They work as standalones, but reading the English and Winslow books first adds context to the relationships and weddings that connect the groups.

Expect romantic comedy energy, family warmth, old secrets, and glamorous settings balanced by characters who need something more honest than a perfect surface.
