The Mark Human series centers on Dr. Mark Thurman, an orthopedic trauma surgeon, and Dr. Claire Hodgson, a leading stem cell researcher. Together they are developing a method to heal bone fractures in days rather than weeks or months. Fractured (2019) kicks off the series when former Navy SEAL sniper John Bristow arrives at the emergency room with multiple gunshot wounds, giving them their first human patient for the experimental treatment. The book was a Kindle Scout winner and a Silver Falchion Award finalist for best thriller at the Killer Nashville International Writers Conference.

Hyperion’s Fracture (2019) continues the story with new threats to their research, and the sequel won the Silver Falchion Award in 2020. Stability Island (2022) is the third installment, pushing the medical stakes higher while maintaining the blend of surgical detail and thriller pacing that defines the series. Author Thomas Kelso is himself an orthopedic surgeon who served in the Navy, and that firsthand knowledge gives the books a level of technical accuracy that sets them apart from most medical thrillers.
