Fallen Blade, book 2: Bared Blade
Kelly McCullough2012

Former temple assassin Aral Kingslayer has a price on his head and a mark on his soul. After his goddess was murdered, Aral found refuge in the shadow jack business, fixing problems for those on the fringes of Tien's underworld. It's a long step down from working for the Goddess of Justice, but it gives Aral and Triss--the living shadow who is his secret partner--a reason to get up in the morning.

When two women hit a rough spot in the tavern Aral uses for an office, he and Triss decide to lend a helping hand--only to find themselves in the middle of a three-way battle to find an artifact that just might be the key to preventing a war. And with so many factions on their trail, Aral and Triss are attracting a lot more attention than anyone featured on ten thousand wanted posters can afford...
