In a parallel-world 21st-century San Francisco where the Kaiser's
Germany won World War One and went on to dominate the world, Paul Gomes
and his father Lawrence are secret agents for our timeline, posing as
traders from a foreign land. They run a storefront shop called Curious
Notions, selling what is in our world routine consumer
technology - record players, radios, cassette decks - all of which is
better than anything in this world, but only by a bit. Their real job
is to obtain raw materials for our timeline. Just as importantly, they
must guard the secret of Crosstime Traffic - for of the millions of
parallel timelines, this is one of the few advanced enough to use that
secret against us.
Now, however, the German occupation police
are harrassing them. They want to know where they're getting their
mysterious goods. Under pressure, Paul and Lawrence hint that their
supplies comes from San Francisco's Chinese... setting in motion a chain
of intrigues that will put the entire enterprise of Crosstime Traffic
at deadly risk.
