There have only been two written so far, out of a planned seven, I believe (five of which he's already signed the contract for). The third is out this fall after a long wait. The second is a confidence game combined with a heist, with a high seas pirate story in the middle. There are some small hints that there may be more traditional epic fantasy happenings much later in the series — Lynch has hinted in interviews that at some point there's going to be a threat to the world, or at least to civilization, and the Bondsmagi of Karthain are set up as fairly big bad guys — but so far he hasn't shown any inclination to tell the stories in a traditional manner.
