Geordie Sharp Books in Order

The Geordie Sharp books are Chris Ryan’s early run of hard-edged, nineties-era military thrillers, centred on SAS sergeant Geordie Sharp. Geordie isn’t written as a superhuman action figure. He’s talented, stubborn, and often in a bad place mentally, which makes his victories feel earned and his mistakes feel expensive.

Geordie lives in that uncomfortable gap between soldiering and everything else: he can plan an ambush, but struggles with what happens when he’s back at base and the adrenaline drains away.

The series opens with Stand By, Stand by, after Geordie is wounded in the Gulf War and returns to Hereford trying to stitch his life back together. His home life is already fragile, and a murder in his family lights a fuse that pushes him toward Northern Ireland and a personal hunt that blurs the line between duty and revenge. The book sets the tone: grief, anger, and the messy consequences of violence.

From there the books keep raising the pressure, and they keep finding ways to make the stakes personal. In Zero Option Geordie is ordered onto deniable “black” work—operations that will be disowned if they go wrong—and then pushed toward a high-level hit on British soil. The threat isn’t abstract either: his four-year-old son is used as leverage, turning the mission into a nightmare where every option is bad.

Nothing stays local for long. The Kremlin Device sends Geordie to Moscow to train a Russian protection unit, where he runs straight into power games, organised crime, and orders with a hidden agenda. By the time the consequences ripple back toward London, Geordie is dealing with enemies who don’t wear uniforms and allies who don’t tell the truth.

Tenth Man Down shifts the action to a poverty-stricken, war-torn African republic, where an SAS team is meant to train government troops but gets dragged into a mess of rebels and foreign mercenaries. There’s even a local prophecy warning that ten foreigners will die, which hangs over the operation like a countdown.

These books run on momentum: gritty, fast, and grounded in soldiering detail, with short chapters, ticking clocks, and the sense that Geordie is always one bad decision away from disaster. Underneath the action, the throughline is what war does to a person who can’t switch it off. If you want to start, read in order from Stand By, Stand by and follow Geordie as the assignments get darker and the choices get harder.
