I'm hooked on Charles Stross books right now.  His series, "The Laundry Files," is a terribly addictive modern fantasy series about a guy named Bob who accidentally discovers that the world of mathematics has opened up a world of excitement.   It seems that high end mathematics has a way of opening up this dimension to a host of other dimensions, and well, a host of unholy hosts.  He gets sucked into the world of "The Laundry," a secret organization tasked with keeping the end of the world from inconveniencing the masses.  Bob goes from being an I.T. consultant to James Bond.  It's Lovecraft meets Ian Fleming meets Office Space.  They're funny, horrifying, and makes you want to learn more about fractals.  Are you going to be more terrified of the cultists of Cthulhu, or the horrible fate that awaits you when you don't have your timesheets properly filled out?
