Billionaire Secrets is a five-book romance series by Ainsley Booth. The first three entries — Personal Delivery, Personal Escort, and Personal Disaster — all appeared in 2017, with The Baby Contract and Too Complicated completing the series. The “personal” theme in the early titles connects the stories through the idea of professional boundaries dissolving into personal entanglements.
The series fits within the billionaire romance subgenre, with each book following a different couple navigating wealth, power, and the messiness of genuine connection.
