Highway to Eternity

the long version

A client had vanished, and Jay Corcoran went to investigate the man's empty hotel suite....his trick vision spotted the room-sized box stuck to the outside wall of the suite. Stumped, he cabled his long-time pal Tom Boone, who could 'step around a corner' into some otherwhere. Boone stepped into the box, taking Corcoran with him....to 1745 England. There they found a family of refugees from a million years in a future....where alien Infinites were converting humanity to incorporeal form....
