When I was a child in the 80s, there was an old picture book at the public library. It had no text, but it took place in a kind of fairy tale castle on some other planet. If I remember correctly, each scene followed two children as they explored the castle. They may have been following a piece of yarn that eventually led them to where their mother sat knitting in one of the castle rooms or towers. There may have been a sort of robotic-looking cat playing with the yarn at some point. I remember the artwork as being full color paintings like you find with 1960s scifi book covers or movie posters.
A large, slow-walking robot is after a guy who has something the robot wants (or he’s after the guy). The robot doesn’t walk around homes or buildings to get to him, but leaves a path of destruction by walking through them, killing people along the way. No matter where the guy goes, the robot will follow.
JUMP TO THE END:
The solution to keep everyone safe is the authorities used a large warehouse and lured the robot to it. A camper, loaded with everything you need to live, had the guy (or the item) in the camper. Because the robot walked so slowly, they were able to drive in a circle and the robot followed forever.
I am hoping you can help me find a book from my childhood. I think it was from the early 80s to mid 90s. It was about a boy that gets an Android robot for a brother. I think they live on the moon in the future. I think one of them has red hair. I believe it was a kid’s series, I was between 10-14 when I read it. I could be totally wrong on how old it was. I think I read the book in 2000 so it could be 1990s too. But I remember the two kids are climbing a tree in it, and I think they were around 12, and lived in a dome on the moon. Again, not sure about this one. I think there were 2 or 3 books in the series.
Thanks for the help!
