Hi all, I had an idea for a story about many worlds and some rare people on each world who can travel between them by magic. I really like the plot I came up with but I don't want to produce an accidental copy. I want to know what's been done so I can try for a fresh spin. In the past, I've had ideas just to find out something really similar already exists, which I'm sure others here have experienced. Does anyone know of books with loosely similar premises or that would be in the same category? The 'travellers' in mine can also travel within worlds so books with Jumper type 'magic' might be appropriate too. I can think of one book I read that fits the bill but I'm satisfied with the differences in that case and couldn't think of any more. BTW, I tried to post this via Tapatalk and it didn't seem to work. So, sorry if it shows up twice. Thanks in advance.
