'Natalie Palladino was a normal fifteen-year-old, at a normal school, about to face a normal maths test. Now her codename is Nomad, and she's training to become a secret agent for HELIX. No one can know that sorcery exists. No one can know that HELIX protects humanity from the Inductors. And no one can know that Nomad is a Witness, with a dangerous magical gift. The Inductors are hunting her. If they find her, they will kill her. But there's a traitor inside HELIX, and only a Witness can identify them. The problem is, Nomad hasn't mastered her powers. She can't levitate, fight or wield magic like her fellow recruits. If she's the only hope to stop a sorcerous bomb being detonated, the world is in trouble. The eleventh hour is coming . . .'

'Red sky at night, sailor’s delight.

'After their mission in London, Nomad, Riff, Phoenix and Orbit are back at HELIX, training to master their magic. But things have changed.

'Nomad’s secret is out. Her peers know she is a Witness; a sorcerer with the rare ability to read others’ magic. This causes ripples at HQ, especially when it means that Steel, the most popular cadet in her class, is no longer the centre of attention.

'But there are greater threats than new rivals. When the cadets are sent to New Zealand to investigate a top-secret case, they find themselves in more danger than they bargained for.

With no one to trust and time running out, it’s a race to stop the Inductors before they have enough power to destroy HELIX for good.
