Oh God... I love good fics about Cybermen and Canary Wharf - I think they are the most awful of any monsters in Doctor Who - and yours is definitely a good one. Your portrayal of bonds created in extreme circumstances was raw and true and I was absolutely captivated until the end - and the end broke my heart a little. I expected that Ianto will be saved too, but it was actually brilliant that he wasn't, it made a point all on its own, and the moment when he was laying on this awful conversion table... Sorry for incoherent review, but I just finished and my emotions and thoughts are still all over the place :)
