The Billionaires’ Club series by Raylin Marks includes nine books published between 2020 and 2025. The series pairs medical professionals with wealthy men, alternating between “Dr.” and “Mr.” titles that suggest a duet structure for each couple.
Dr. Mitchell (2020) and Mr. Mitchell (2020) launch the series as a paired set, followed by Dr. Brooks and Mr. Grayson (2021), Dr. Brandt and Mr. Monroe (2022), and Dr. Aster and Mr. Aster (2024). Dr. Stone (2025) is the most recent entry. The alternating title pattern gives readers two perspectives on each romance, and the series has grown into Marks’ most extensive body of work.
