The Whitefire Crossing

Shattered Sigil Trilogy by Courtney Schafer for you Gentleman Bastards fix. You want likeable characters? You get them and then some. You want cons and clever lies? Just you wait. The cast is focussed (two protagonists and and a small assortment of sidecharacters/villains), the story is very engaging and moves at a brisk pace. As a bonus, the trilogy is finished and not only do the stakes get higher, Courtney's skills get better with each book like she's some kind of crazy writer Pokemon. And yes, the characters grow with each book.
