I've liked the two Mercy books I've read because Mercy actually talks to people. There is (relatively speaking) very little "I'm going to go battle this Big Bad on my own!" -- even if she does do that, for the most part, she makes sure she's left messages and notes telling people what she's up to and why. She's big on involving allies in general, which is good.

And yes, the Jim Butcher books are awesome. Even though werewolves and vampires make the occasional appearance, it's a very different take than the "romantic" angsty stuff that seems to be flooding the field.
