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

The man Moffat does it again....
8 June 2008 | by (England) – See all my reviews

Whenever I think of the future of "Doctor Who" in the hands of one Steven Moffat, I have a warm glow in my heart. Without a doubt, Moffat is one of the most talented writers the series has ever attracted (and a massive talent outside the series). One wonders what delights his "Tintin" script will deliver...

The second part of the library tale manages to trump the first episode. Without going into any details, it's all clever stuff and emotional too.

The cast are splendid and Alex Kingston's River Song adds a whole new layer to the series.

9 out of 10. Fantastic entertainment. Expect a BAFTA, Mr. Moffat...
