The Recommended Reading Order
The Quantum series, written by New York Times bestselling author Marie Force under her erotic romance pen name M.S. Force, is a contemporary romance saga set against the glamorous backdrop of the entertainment industry. The series revolves around the founders, actors, and executives of Quantum Productions and their BDSM-friendly private club, Club Quantum. Because the books feature a tightly knit group of colleagues and friends, the relationships and overall company plotlines progress linearly. Therefore, the absolute best way to experience the series is in publication order.
- Virtuous (2015) – Introduces movie star Flynn Godfrey and NYC schoolteacher Natalie Bryant.
- Valorous (2015) – Continues Flynn and Natalie's intense, whirlwind romance.
- Victorious (2015) – The conclusion of Flynn and Natalie's core trilogy.
- Rapturous (2016) – Follows Quantum director Hayden Roth and production designer Addie Valens.
- Ravenous (2016) – Follows Quantum partner Jasper Cawthorne and author Ellie Sterling.
- Delirious (2017) – Focuses on Quantum's chief financial officer Kristian Demetrious and Aileen.
- Outrageous (2018) – Focuses on Emmett Murphy and Leah.
- Famous (2019) – Focuses on Oscar-winning actress Marlowe Sloane and Sebastian.
- Illustrious (2025) – Revisits Flynn's parents, Max Godfrey and Stella Flynn, as a memoir threatens their fifty-year marriage.
The series will continue to expand with the upcoming tenth installment, Momentous, featuring Olivia, scheduled for release in 2026.
Chronological Order and Timeline Structure
The chronological order of the Quantum series mirrors the publication order. The first three books (Virtuous, Valorous, and Victorious) function as a continuous trilogy that must be read sequentially, as they tell a single overarching story of Natalie Bryant and Flynn Godfrey. Following the conclusion of their trilogy, the books transition into standalone romances, each spotlighting a different member of the Quantum team. While the standalone books can theoretically be read in any order, characters from previous books frequently make appearances, and the found-family dynamic of the Quantum crew evolves with each story. The timeline progresses steadily from 2015 through 2019, followed by a six-year narrative jump to the events of Illustrious in 2025.
Understanding the Heat Levels: Tame vs. Original
One of the most unique aspects of the Quantum series is the availability of two distinct reading tracks depending on your preferred level of sexual content:
- The Original Series (Nuclear Heat): Published under the pen name M.S. Force, these editions feature highly explicit BDSM dynamics, kinky encounters, and high-heat romance on the page.
- The "Tame" Quantum Series (Toned-down Heat): For readers who want the exact same emotional character growth, storylines, and Hollywood drama without the highly graphic content, Marie Force created "Tame" editions. In these versions, the kinky preferences and BDSM lifestyle of the characters are still discussed as vital plot points, but the explicit scenes occur off-stage, keeping the romance at a more conventional "hot and heavy" level.
If you purchase the digital editions of the original books, the "Tame" versions are often included as a bonus in the back of the ebook, accessible via the Table of Contents. Dedicated "Tame" boxed sets are also available for purchase.
Detailed Book-by-Book Breakdown
The Flynn and Natalie Trilogy (Books 1–3)
The series begins with Virtuous, where Hollywood superstar Flynn Godfrey meets schoolteacher Natalie Bryant after her dog, Fluff, bites him in a New York park. Flynn is immediately captivated by Natalie's innocence and down-to-earth nature, but he harbors a secret life as a dominant in the BDSM community. Natalie, who is recovering from her own past trauma, is thrown into the intense spotlight of Flynn's celebrity lifestyle. Valorous and Victorious follow the couple as they build deep mutual trust, navigate paparazzi intrusions, and solidify their commitment, establishing the foundational setting of Quantum Productions and the tight group of friends who run it.
The Standalone Romances (Books 4–8)
With Rapturous, the spotlight shifts to Hayden Roth, a dominant director who meets his match in Addie Valens, a woman who challenges his control and forces him to confront his own emotional vulnerabilities. Next, Ravenous follows Jasper Cawthorne and Ellie Sterling in a marriage-of-convenience arrangement driven by Ellie's desire to have a baby, which quickly spirals into genuine, high-stakes passion. Delirious focuses on the company's CFO, Kristian Demetrious, who views intimacy as a game until he meets Aileen, who rewrite the rules of his life. Outrageous explores the fiery relationship between Emmett Murphy and Leah, while Famous details the journey of fierce Hollywood icon Marlowe Sloane as she finds love and equilibrium with Sebastian, subverting traditional BDSM roles.
The Next Generation & Legacy (Book 9)
Released in 2025, Illustrious serves as both a reunion for the series characters and a prequel-sequel hybrid. The book turns its focus to Max Godfrey and Stella Flynn—Flynn Godfrey's parents and Hollywood royalty in their own right. When a scandalous tell-all memoir threatens to tear apart their fifty-year marriage, the entire Quantum crew rallies around them, highlighting the enduring bonds of the found family.
Spin-Offs: Remington Family Law
In 2026, Marie Force launched the spin-off series, Remington Family Law, beginning with the novel Acrimonious (followed by Contentious). This series centers on the nine Remington siblings, who are all family law attorneys determined to avoid marriage after witnessing their parents' toxic custody battle. Julian Remington, the protagonist of Acrimonious, visits the underground BDSM sanctuary Club Quantum to blow off steam, cementing the crossover connection between the two series and giving fans of the original Quantum books a look at their favorite club from a fresh perspective.
Practical Reader Advice
For the best reading experience, start with Virtuous. Skipping the first three books is not recommended, as the world-building, the establishment of the Club Quantum setting, and the core relationships of the side characters are all set up during Flynn and Natalie's trilogy. Once you finish Victorious, you can read the subsequent titles as standalone romances, though reading them in order ensures you won't spoil the romantic outcomes of the other Quantum partners. Before purchasing, verify whether you are buying the original explicit version or the "Tame" version depending on your reading preferences.
