The planet Bienvenido is in crisis. It has finally escaped the Void, emerging into regular space. But it's millions of light-years from Commonwealth assistance, and humans are battling the Fallers for control of their world. This rapacious adversary, evolved to destroy all sentient life, has infiltrated every level of human society - hijacking unwilling bodies so its citizens fear their leaders, friends and family. A mysterious figure known as the Warrior Angel leads a desperate resistance. She's helped by forbidden Commonwealth technology, which gives her a crucial edge. But the government obstructs the Angel's efforts at every turn, blinded by prejudice and technophobia. As Fallers also prepare to attack from the skies, she might need to incite rebellion to fight this invasion. But the odds seem impossible. Then astronaut Ry Evine uncovers one last hope. On a mission against the enemy, his spacecraft damages an unidentified vessel. This crash-lands on the planet carrying unexpected cargo: a baby. This extraordinary Commonwealth child possesses knowledge that could save them all. But if the Fallers catch her, the people of Bienvenido will not survive.
