Ryan Kaine’s 83 is Kerry J. Donovan’s flagship action thriller series. It follows Ryan Kaine, a former Royal Air Force officer who is falsely accused of involvement in a terrorist attack that kills 83 people. Forced to go on the run, Kaine must use his military training to survive while working to uncover the real conspiracy behind the attack.
The series began with On the Run in 2017 and has grown to fourteen books. Each installment picks up where the last left off, with Kaine facing new threats and getting closer to the truth. The “On the…” title pattern runs through the entire series, from On the Rocks and On the Defensive through to On the Trail in 2025.
Donovan writes fast-paced action sequences grounded in military detail, and the series has drawn comparisons to the work of Lee Child and Vince Flynn. A companion series, Ryan Kaine’s Origins, provides additional backstory and alternative perspectives on many of the events from the main storyline.
