You've Got Murder

By Donna Andrews

Turing Hopper, an artificially intelligent computer program, notices that her workaholic designer, Zack, is missing.  She checks everywhere for his electronic footprint, with no luck, then decides to enlist the help of two human friends to do some actual legwork.  It seems Zack is nowhere to be found, and some other apparently dangerous people are looking for Zack too.

I liked this far more than I thought I would, mostly because I liked Turing.  I imagine her as the "good" AI character, as opposed to the typical "evil" AI trying to destroy humankind.  Turing liked people, and wanted to be more like them.  Slightly more serious than Andrew's previous books but still fun.
