Aidan Snow Books in Order

The Aidan Snow books follow a British soldier who never quite leaves the battlefield behind. When we first meet Snow he is a young SAS trooper, confident and effective, working as an instructor and leading a team of Polish recruits on what should be a straightforward operation. A convoy ambush, a bank raid and a green eyed enemy soldier change everything, leaving him badly wounded and convinced he is about to die.

Years later, at the start of Cold Blood, Snow is teaching at a school in Kyiv and trying to live a quiet life. He walks on a bad leg, carries the weight of the past and drinks more than he should, but he has built a routine he can live with. That fragile peace is shattered when Taurus Pashinski, the man with green eyes who once stood over him in the wreckage, resurfaces as a powerful trafficker moving arms and drugs across Ukraine.

Snow is pulled back into violence as friends and students are threatened. The novel sets the template for the series. Personal history and unfinished business collide with organised crime, corrupt officials and overlapping intelligence services. Snow’s background makes him dangerous, but his years as an expatriate in Kyiv also give him contacts and language skills that few Western agents can match.

In Cold Black, Snow has formally joined MI6 and is sent to locate an old SAS colleague who may hold the key to stopping an al-Qaeda splinter cell. The search uncovers a web of funding and influence that stretches from Eastern Europe into the Middle East and the global energy trade. Once again Snow finds himself in a maelstrom where decisions taken in offices in London or Riyadh are paid for in blood on the ground.

Cold East raises the stakes further. Russian backed insurgents in Ukraine hold a British citizen hostage just as word emerges that terrorists have obtained an RA-115A, a portable nuclear device left over from the Cold War. As the CIA and MI6 scramble to track the weapon, Snow moves between Ukraine, Russia, Afghanistan and the United States, trying to piece together a puzzle in which every delay could mean mass casualties.

Shorter works deepen this world. In Hetman: Donetsk Calling, Snow rushes to Kyiv when an old friend, British expat Brian Webb, is shot at on his way home from a night out. What begins as a personal favour turns into a confrontation with armed gangs and the city’s murkier power structures. Kyiv Rules shifts focus to Gennady Dudka, an ageing officer in the Ukrainian security service facing a series of armoured car attacks and pressure to retire just before an international conference. His determination to prove he still has what it takes shows another side of the same universe.

Across the Aidan Snow series, readers get fast moving plots filled with kidnappings, terror cells and high stakes operations, but also a strong sense of place. Kyiv, Moscow, London and the deserts of Afghanistan are drawn from lived experience rather than postcards. Snow himself carries scars, makes mistakes and questions his orders, which gives these thrillers an emotional weight beneath the explosions and gun battles.
