I'm not done saying how awesome the 20 Palaces series is. Nope. Not done.
It's what I think they in the book world call an "urban fantasy" novel. Which basically means fantasy elements (in this case, magic) in a modern world.
And the world is set up very strongly. Like what I call a "you can kick it" world where the reality holds up even later when you're thinking about it while taking a shower or whatever.
The characters are really fun and interesting. Our protagonist is a dude who just got out of jail for stealing cars. That makes him a former car thief. And that's quite useful skill-wise, actually, for a dude who does what he needs to do.
But the thing that's most groovy is that structurally the books do not let up. There's no room for a breath. We slam right into the story and keep going.
Seriously, this should be a TV series. You shoot it Law&Order style in New York.
