I really hope someone can help me. There is a book I read years ago and cannot remember the name of it but would love to read it again.
If I remember correctly it was about people living in a tree and they would get into a bubble or something like that to move up the tree. People thought they were dying but it turns out they were moving up a level in life.
Apparently the same author wrote a story about someone digging up an old teacup handle that is about 3 meters long but it turns out the human race was modified and are now tiny.
Hope I haven't made all this up because they sound like crazy ramblings.
