Donna finds herself in a world where she is happily married and has two children. She has virtually no memory of what may have happened to her in the Library or anything prior to that in the real world. When she does get a glimpse in her mind of her past life, it is quickly shut down. In the Library itself, the Doctor and Professor River Song try to find out what happened not only to Donna but to the over 4000 people the computer says were saved when the library was shut down 100 years ago. The solution to it all lies in understanding what the computer has been telling them all along. Written by garykmcd

Best of the season?
9 June 2008 | by (Australia) – See all my reviews

My answer is yes. This out does all the previous episodes this season and does so much for the feel of Doctor Who. With the inclusion of the Doctors future Moffat brought me to tears. I was literally crying as the finally played out. A great ending too as it left you wanting more and also feeling content that the story had met its ending (I know weird, mind you maybe that is because I always want more Doctor Who). All the actors created such great support too for the story to flow. This episode definitely exceeded Silence in the Library and gave it the best ending it possibly could. When I first saw the trailer (after The Unicorn and the Wasp) I was thinking "What a silly idea, shadows in Libraries" but once I saw that Stephen Moffat wrote it I knew that this would produce a great two episode arch. I can't wait for Moffat to become Executive Producer. Mind you the waiting for this episode was nearly unbearable.

Not wanting to spoil I have to end it there, I would never stop if I don't.

A great episode, going to watch it again right now.
