The Unholy Trinity is one of Donna Kauffman’s longer series, with ten entries published between 2007 and 2023. The series began with The Black Sheep and the Princess (2007) and continued with The Black Sheep and the Hidden Beauty and The Black Sheep and the English Rose (both 2008). Later books like Witch’s Betrayal and Witch’s Exile (both 2018) added paranormal elements to the mix.
The series has an unusual publication history, with long gaps between some entries and a shift in tone from contemporary romance toward paranormal territory over time. The most recent entry, Mila, arrived in 2023, showing that Kauffman has continued to revisit this story world over nearly two decades.
