A Siren - Previously...

At the American Entry-Point, Gutteridge and his covert team infiltrate behind the lines of the Exile blockade and capture an enemy Fieldship. Now they must attempt to fly it back to their Entry-Point.

Back in the Exile Fortress, Alex is confronted by a deranged Dr. Henschel, who helps him escape from his cell. Henschel reveals that it has been he, not Alex, under the influence of the Demon Girl, and in a moment of lucidity has destroyed the Exile Array and opened up the Fortress to the attacking Demon army. Alex makes for Hangar 13, where Henschel has a Fieldship waiting to aid his escape.

Meanwhile, at the Maunsworth Entry-Point, the expedition is still under attack from the Exile soldiers. Grace and Thomas, separated from the group attempt to hide in the ruins, but Thomas is shot by an Exile soldier and his suit is breached. As he is overcome by the atmosphere of the Field he spies a mountainous figure who comes to their rescue.

Thomas awakens to find himself in the company of an entity he calls an angel, who heals his wounds and repairs his suit. Thomas returns to the Field, and finds Grace. Together they head off into the howling sandstorm...

At the Maunsworth Entry-Point, the British expedition is exploring the strange world of the HeavenField. While looking over a newly-discovered collection of buildings, they are attacked by a group of Exiles.

The main security force, along with Gary Starling and Stuart Nicks, are forced to engage them in a fire-fight. But Grace and Thomas find themselves split from the group, and run further into the ruins in a desperate attempt to evade their pursuers.

Meanwhile Speers' American Accelerator Array is complete. His newly-formed army enters the HeavenField, only to discover their Entry-Point encircled by a force of Exile soldiers. Speers though, ever-more delusional, clings to his belief that it is the British who are attacking.

Realising that their adversaries have access to far-superior technology, Speers orders Gutteridge to lead a covert team into the Field in a desperate attempt to capture and return with an enemy Fieldship...
