The Fifteenth Doctor and Belinda return in a new story from BBC Books as they are set to embark on The Moon Cruise this November.

Written by Esmie Jikiemi-Pearson, previously known for the novelisation of 2023 Christmas special The Church on Ruby Road, this novel is the third original Fifteenth Doctor novel released in 2025, accompanying recent releases Fear Death by Water by Emily Cook and Spectral Scream by Hannah Fergesen.

The TARDIS lands on board a luxury space liner owned by the interstellar shipping magnate, Marilyn Moon. The Moon Cruise offers its wealthy passengers up-close views of astounding cosmic wonders and the Doctor and Belinda are soon high rolling it on the top deck.

But there is a sinister side to life on board. What is the secret of the smiling, blonde-haired mannequins? What happens to the cruise ship workers when they go off shift? The Doctor soon learns that not all prisons come with bars on the windows, while Belinda faces one of the greatest cruelties in the universe – a zero-pay contract in retail and hospitality that can never be broken…

The Moon Cruise is available for pre-order in hardback or audiobook version for a 13 November 2025 release.
