Epic Fantasy - Contemporary Earth Setting?

[MClark]

What about the works of Tim Powers? Declare seemed pretty epic to me. Djinn, Mt Ararat, Cold War espionage, not sure how to get more epic than that. Last Call about Tarot cards and Bugsy Siegel creating Las Vegas.

 The Stress of Her Regard is about a writer's muse as vampire, but takes place in the early 19th century.

The Case of the Toxic SpellDump by H. Turtledove
Though this is set in a world where there is magic it's very much like our world.
You have bureaucrats and politics and protests, and stuff we deal with just with
things being magical.
The hero starts out checking out a - toxic spell dump - which is just that - a place they dump
the hazardous remains of magical conjurations and the like.  He ends up discovering that
really bad stuff is about to happen and has to take steps.
It goes from everyday to epic.
