Doctor Who: The Day She Saved the Doctor is an anthology that tells four tales from the Doctor's four companions. Sarah Jane Smith, Rose Tyler, Clara Oswald, and Bill Potts. Each story is from the companions point and all four stories put you right there with the companions. With Sarah Jane Smith you feel like you're right there with the fourth Doctor as they take on a cult. With Rose Tyler The Doctor takes her to Vancouver in order to stop a rip in time and space that opens up into the 1800's in order to close that rip. With Clara, she and the Doctor take a trip to a planet where a maze has caused the death of it's inhabitants. With Bill, she is lured into a shop where a shapeshiftier takes her body and almost her mind. This is a great anthology and I highly recommend it for all Doctor Who fans.
