Outside of the superficial stuff (they're both mages in the modern world who have a problem with authority and a large part of the overarching story is about power struggles within the main political structures and all that) they're pretty different. Dresden is a good guy with a ton of power so while he's always up against threats a lot bigger than he is, he's always able to fight back effectively and overcome it. In comparison, Verus doesn't have that kind of magic and can't compete, so by necessity he has to become much more opportunistic and ruthless, he's a very morally-grey character, possibly slipping down over the line and becoming irredeemable.

I really enjoyed it and strongly recommend it. It's even finished, so you don't have to wait years as the story unfolds! 12 novels and 2 novellas and you're done. One is set at the halfway point, but I read them both at the end and thought it was probably better that way than if I'd read it chronologically, up to you.
