I'm trying to find a sci-fi story I read in the mid 80's which I think was for roughly the 10-15 age range. Things I can remember:
- I think the protagonist was a teenage boy. He might have had a dog.
- There had been an alien invasion which had destroyed most of society, with only small groups of survivors trying to fight back
- The aliens used drones such as flying robotic birds with flame throwers that hovered in the sky and hunted for survivors.
- Set in the UK possibly, but I might be conflating that with John Christopher's Tripods books which had a similar feel and that I read about the same time.
- They captured one of the 'birds' at one point and discovered it was full of a red gelatinous substance : some kind of alien technology for controlling the machines
- I think no-one had seen the aliens, which were a mystery (at least at the start of the book), but that might also be conflation with the Tripods.
Not a whole lot to go on I'm afraid.
