Synopsis: From the back cover of the Ace first edition: "A common cause... uncommon allies. Summer, 1945. The war in Europe is winding down, but thanks to their alliance with the gnome-owned, dwarf-run Nieuw Amsterdam Metalworks, Plimstubb Industrial Furnaces still has all the business it can handle. Some of their clients might be a bit - odd - but work is work, and Grady Cavanaugh is happy to have a job.

And the machines they have provided are very, very dangerous. Now Grady and his dwarf friends must find and disable them. There are lives at stake - even more than Grady can imagine..."
