Summary (via Goodreads):  

In Tira Virte, art is prized for its beauty and as a binding legal record of everything from marriages to treaties. Yet not even the Grand Duke knows how extraordinary the Grijalva family's art is, for certain Grijalva males are born with the ability to alter events and influence people in the real world through that they paint. Always, their power has been used for Tira Virte. But now Sario Grijalva has learned to use his Gift in a whole new way. And when he begins to work his magic both the Grijalvas and Tira Virte may pay the price.

I picked this up sometime last year because it looked interesting -- I haven't read anything by the authors before, but this seems right up my alley. I think the length's been putting me off (it's over 800 pages in MMP format), but one of these days I'll get to it. The world-building sounds too cool to pass over.
