Just came up with a brilliant premise. Please someone write it! Add your own ideas here for stuff you think of but don't really want or know how to write! And then add a link to the book or short story. ☺️
A 5 year old goes missing. Unbeknownst to the parents, he/she has been pulled into a parallel universe. The child doesn't know it, because the other universe is exactly the same, including the way time works.
Meanwhile, the child's twin is still at home. When twin A returns two weeks later, he/she is 30 years old.
