The Unexpected series by Lilian Monroe is a large collection of 14 romances connected by the surprise-pregnancy theme. The series includes both contemporary settings, like Knocked Up by the CEO and Knocked Up by the Single Dad, and royal settings, like Bad Prince and Heartless Prince. Several of the entries overlap with the Royally Unexpected series, tying the two collections together.
The series spans books published from 2018 onward. Each entry features a different woman and the man whose life she upends with unexpected news. The mix of billionaire, royal, and everyday settings gives the series variety within its core premise.
