In space, something can hear you scream. And that something is coming.

On her first adventure in outer space, Ruby learns that the universe is bigger, more colourful, and crazier than she could ever have imagined. She also learns that even the Doctor can feel afraid – and that certain nightmares are all too real…

A new voice to Doctor Who fiction, Alison Rumfitt, presents the Target novelisation of Russell T Davies’ first space adventure for the Fifteenth Doctor and Ruby Sunday, as played by Ncuti Gatwa and Millie Gibson.
