Author's Summary:
The 456 are Junkies. Highly intelligent Junkies, with lots of blissed out time in which to think up more ways to get their fix. Why would they gas a building full of people who may yet live to create more children? The gas is more than anyone knows, and its reaction to one Ianto Jones is more than anyone, even the 456, could have thought.
Ianto has lived next door to the Rift since he was born, and has encountered so many different kinds of energy that it shouldn't be a surprise that an Alien drug would have an extreme effect on him, but it is anyway.

Review:
I put off reading this one for a long time because of the series title and how terribly slow it is to get started, but get through the intro and it's actually full of world-building, interesting details (including the appearance of Mainframe) and has Ianto being all kinds of awesome, basically resurrecting Torchwood in secret on his own using whatever resources he'd prepared in advance or collected knowledge of over his years at Torchwood.  Aide de memoire - this is the on where all the Thames House victims are brought back as children, Owen and Tosh and Steven mysteriously come back, and Ianto returns as a child and every time he dies, he returns randomly aged 8-26.  As creative and re-read-worthy as this fic is though, it's a little plodding at times and there isn't enough of it to really develop into a proper story - I really wish there was more, but it appears to be abandoned.
