Winter Dawn Alex Callister

Meet Winter: she's the audacious, hyper-intelligent GCHQ agent with more notches on her bedpost than James Bond and more hacking cred than Lisbeth Salander.

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. It's the winter solstice and as they journey together into the dark heart of the longest night, they soon discover that nothing about Colosseum is what it seems.

There are rules and there is a purpose, if only they can solve the riddle in time. Colosseum is more than a hunt: it's a challenge. Targets must face their darkest fear or die at dawn.

Winter Dawn is the third instalment in the Winter series - the first of which was Audible's Thriller of the Year in 2019 - and journeys back to the beginning of her story.
