'Kirra Hayward is an ordinary sixteen year old - smarter than most, but otherwise completely anonymous. When she stumbles across an unusual puzzle on the internet and manages to solve it, she has no idea of what she's letting herself in for. Kidnapped by a shadowy organisation known only as The Industry, Kirra soon discovers how valuable her code-breaking skills are. And when she stubbornly refuses to help them, they decide to break her ... by any means at their disposal. Kirra knows that to protect herself, she must trust no one, not even her fellow prisoner, Milo. But as time goes by she realises he might be the only person she can rely on ...'

'Kirra Hayward has many questions. What is the Estate? Will she be safe from Latham there? Will her code cracking skills be used for good or evil? Will she ever make it home?

'As she reluctantly joins the ranks of criminals, Kirra begins to realise the Estate isn't quite the place of refuge she hoped it would be. There's a bully to avoid, rumours of a second code cracker on the run, and the feeling that someone at the Estate wants Kirra gone.

'For good.' (Publication summary)
