I am looking for a book about aliens ruling Earth and there is an underground rebellion. I read this over 20 years ago, so only certain parts stick in my mind.
I believe it took place on the west coast of North America, and the book may start in Northern California or even San Francisco.
The book starts with a raid against the human rebels. A boy escapes. This is the main character throughout the books. I believe there were other aliens as well that are described in the book and one of them is globes sitting on top of other globes.
I want to say the spaceships used by the aliens are triangular, but I could be wrong. I think the humans win, but can't be certain. I believe there is a part in the woods where they confront the aliens in a base or something similar.
