A Night in Terror Tower

While touring the Tower of London, American siblings Sue and Eddie are stalked by a mysterious man in black and mysteriously transported back to medieval times.

There, they discover they are royal children marked for execution by the Lord High Executioner and must use magical stones to return to the present.

Loosely inspired by the historical Princes in the Tower, the story blends horror, adventure, and time travel in classic Goosebumps style.
