Cerberus Personal Security is one of Ellie Masters’s newer series, launching in 2025 with Ghost. The books follow operatives at a private security firm, continuing Masters’s specialty of pairing protective heroes with women in danger.
Each book features a different operative at the Cerberus firm. Ghost (2025) and Brass (2025) kicked things off, followed by Whisper (2025), with Fuse and Halo extending into 2026. The titles match operative code names, and each story pairs one agent with a new love interest while weaving in the broader security firm setting.
Masters has published more than fifty romance novels, and she returns often to military and security themes. Readers who enjoyed her AEGIS Group or Guardian Hostage Rescue series will find Cerberus Personal Security follows a similar structure of tough heroes and high-stakes situations.
