On one side, the military might of the United States and Air Commodore Fiona Bardock, Britain’s most talented investigator. On the other, three halfheroes, one human, and a puddle of slime. Daniel Harbin hopes to get through this alive and track down the children he never knew existed.

 

What no one realises is they’re about to confront the greatest danger of all.
