I particularly recommend Stross's The Jennifer Morgue (novel-length sequel to The Atrocity Archives), Singularity Sky, and The Family Trade and its sequels. Oh, and Toast, which is a collection of short stories. Just don't read "A Colder War" late at night. ("What if the superpowers in the Cold War had been able to bind Cthulhu and related powers?" It doesn't end well.)
