When Danny's best friend Jamila goes missing, and no one remembers she exists, Danny knows the alien Swarm are back on Earth. They've tracked the digital energy signals Jamila has been unintentionally transmitting.

Her alien-enhanced DNA can be used to clone super-strong beings with super-powers, and now it's not just the Swarm who are after her. Danny needs to find Jamila - and a new version of Adi, the friendly Swarm scout - and together they must stop both humans and aliens from destroying the human race.
