I guess Connelly (e.g. with the Bosch novels) always mixes courtroom / legal drama with cop / detective adventure. That is true here as well, although the main character is probably more ethically gray than Bosch at his grayest.
I did like the theme most of Haller's clients were not actually evil. They might be thugs, but Haller makes a distinction between trying to get by and making some bad choices, and actual evil.
Long suffering ex wives seem to be a theme with Connelly. Possible author life spoiler there?
I did zip right through it, so it might be a perfect read for sitting on the front porch in the summer.
