Vows of Sin is a five-book series published across 2024 and 2025 in which every hero is a duke with a sinful reputation. Her Sinful Duke, Wedded to the Sinful Duke, A Bride for the Sinful Duke, A Sinful Virgin for the Duke, and The Duke’s Sinful Bride each follow a different couple through a romance shadowed by the hero’s past transgressions. The series leans into the “reformed rake” trope that is a staple of Regency romance.
