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.

Alison Rumfitt is a writer and cultural critic. Her two horror novels Tell Me I'm Worthless and Brainwyrms push the boundaries of both taste and form to the shock of readers everywhere. She has written for Little White Lies and Dazed, and interviewed new Doctor Ncuti Gatwa for Rolling Stone. She's considered herself a fan of Doctor Who ever since her father played her the theme song to scare her when she was about five years old.
