R.D. Brady is the bestselling author of over 60 science-based thrillers, cryptid adventure novels, and mythological conspiracy series that blend real-world science with nonstop action.
With a Ph.D. in Criminology and a professional background in counterterrorism and behavioral science, R.D. brings expert insight to her fast-paced fiction. Her stories are known for featuring fierce female leads, ancient secrets, and cutting-edge research that challenges what we think we know about science, history, and the unknown.
She is best known for the long-running Belial Series, a fan-favorite that explores archaeological mysteries and supernatural revelations—and continues with the high-stakes Belial Rebirth Arc.
R.D. is also the author of The Ancestral Code Series, starting with Hominid, a cryptid-meets-science thriller that reimagines the Bigfoot legend. Her other popular works include the A.L.I.V.E.

Whether it's a global genetic conspiracy, an ancient civilization buried beneath modern myths, or a killer storm trapping a wrongly accused man, R.D.'s books deliver the adrenaline, mystery, and emotional depth that fans of Michael Crichton, Douglas Preston & Lincoln Child, and James Rollins crave.
When not writing, R.D. teaches martial arts, runs with her dogs, and tends to her garden. Under the pen name Sadie Hobbes, she also writes sharp, fast-paced urban fantasy thrillers.
