A rather bleak and dismal look at human trafficking in a future where the victims are cybernetically modified on the other side of a trans-dimensional portal. I'm not entirely sure if it was my unfamiliarity with British slang or the author's style, but it took a long time for me to find the rhythm and really get into the book; that, coupled with the near-total lack of joy or any form of happiness, made this one a bit of a slog for me.
