Unholy Trinity Books in Order

Unholy Trinity is one of Donna Kauffman's sleeker, more high-gloss contemporary setups. The series follows the so-called bad boys of Trinity Inc., men with money, attitude, and just enough trouble around them to make every romance feel like a collision rather than a meet-cute.

The books play with privilege, reputation, and attraction in a big way. Heiresses, hidden agendas, theft, old grudges, and glamour all show up here. In The Black Sheep and the Princess, childhood history and class expectations are already loaded before the couple even has a real conversation. By The Black Sheep and the English Rose, the story is juggling jewel theft, old desire, and two people who should know better and absolutely do not behave accordingly.

That is the mood across the whole set. These are not cozy small-town books. They are fast, sexy, slightly over-the-top contemporary romances built around confident leads and messy entanglements.

And usually fighting it first.

If you want the bad-boy side of Donna Kauffman, with more glamour and more edge than her later community romances, Unholy Trinity is a good lane to explore.
