Captain Jack's the poster boy, Ianto's the style, but Eve and Kai are the heart of Torchwood. Listening to the two of them back together is an utter joy. We pick up their story after Miracle Day. How has life been treating them? It's a delight to find out.

I still can’t believe that I’ve been asked to write a story for the brilliant characters of Gwen and Rhys. I’ve been lucky enough to write for Eve before, on Belonging, and I know that she has a unique gift of imbuing every syllable with the deepest meaning. Getting Eve Myles and Kai Owen, too, is basically like winning the writer lottery.
