This book was written by Amelia Williams (Pond) and was referenced in The Bells of Saint John episode of Doctor Who. While it’s not directly a Doctor story the character of Barnabas was clearly inspired by the Doctor. There’s a lot of clever little references to catch knowing who “wrote” this story. Overall an enjoyable short read, but definitely more of a children’s story than the usual Doctor Who tie in novels.

Audiobook: Clare Corbett is a frequent Doctor Who book narrator and is particularly suited for this story and does an engaging job.
