"The Stars My Destination" is a novel that has some really interesting explorations for how instantaneous teleportation (or, as the book's universe terms it, "jaunteing") would be made practicable. There have to be specific landmarks and town squares people can teleport to or else they can't go there. Also some people can travel for thousands of miles in one jump while some can only jump a few metres. And a tragic few can't do it at all.<br><br>It's a brilliant novel with a really well-imagined world. Definitely give it a read if you can.
