Amusingly, the cover of The Quantum Thief (at least on iBooks) has the following quote:

> "The best first SF novel I've read in years. Hard to admit, but I think he's better at this stuff than I am." -Charles Stross

Seconded, in the beginning it almost has a fantasy vibe since what it describes for the most part is so advanced it almost seems magical, but stick with it because it is fantastic.
