hi everyone, help needed!
I am want to find these books which I loved as a child, but cannot recall the titles, it has been many decades )
1. A group of friends build a camp or castle on a hill in the middle of a patch of wasteland, and have to defend it against a rival group or developers...
2. A series based on a boy whose father owns a spaceship shipping company, not sure earth based or some imaginary world but there were many books,
thanks a lot for any suggestions, they were my reading as a 7 to 10 year old and I want to find them for my niece.
Alex
