GCHQ agent Winter has just 14 days to bring down a website before a teenager is tortured to death in front of an internet audience of millions. Winter has to go deep undercover, disguised as the paid assassin Snow White, to infiltrate the criminals’ organisation and bring down the man at the heart of the dark web. Winter is razor-sharp, quick-witted and sexy, an expert in all forms of combat, master hacker and the number one field agent of British Intelligence.

The sequel to Winter Dark sees the return of Winter – and this time she has her work cut out. With only a week to go until the world's leaders convene for a summit in London, she is hot on the trail of the Guardsman, Firestorm’s top hitman. What is he planning for the summit and what are the disturbing experiments he is running? From London to Virginia, Marseille to Moscow, just how do all the strands connect? What is the final countdown and who can she really trust?

Winter Dawn is the third instalment in the Winter series, journeying back to the beginning of her story. This time, she’s grappling with Colosseum: a sinister online phenomenon that has gripped the world. It promises a massive cash prize to the successful hunter of its victims, unleashing an unstoppable tide of violence - and the world’s authorities are powerless to prevent it. When a New York senator is targeted, Winter is called in to protect her. But with all the world watching, there’s nowhere to hide. No one has ever survived Colosseum.

Firestorm is down – the assassin for hire website that had the world by its throat, gone. Alek Konstantin, king of the underworld, is in hiding. But while the world celebrates, Winter is bracing for what must surely follow. All the world’s cut-throats, assassins and thugs are unemployed, roaming the globe without a leader - and nature abhors a vacuum. Something’s not right, and it’s not only that Winter’s body is in pieces. A boy held captive. An attempted assassination. Thirty men gunned down in rural South Wales.

Sex, violence, murder, betrayal, revenge and a kick-ass unstoppable heroine with one big Achilles’ heel. That would be Winter. She’s been having kind of a bad week... Firestorm 2, the plot to mine data from the infamous murder-for-hire website, has been a success. But while Winter’s been held prisoner by Alek after saving his life, GCHQ has been ordering hits to eliminate every contractor on the site – and leaked footage of Alek and Winter together means she’s now public enemy number one.
