I am planning to buy it (it's not that easy here at all) but I don't really know if it's worth. I mean the DT series is whole without it as well (to me) but I might feel this way because I haven't read this one yet.
So?
Does it give back the DT-series-feeling?

And some more stupid questions:
Can I buy only this very short story or can it be found with other short stories in the book?
