Re-read 29/9/2016 -I love this book so so much! I have a full review on another edition as well XD 
 Kaz brecker has worked his way up from the slums, building himself a network of thieves and gamblers and controlling a dock so his crew get first pick of the tourists visiting Ketterdamn looking for booze, woman, and gambling dens. 
 Inej is known as the wraith, she can move with out a sound and follow someone without them ever knowing, she's the eyes and ears of Ketterdam working for Kaz and looking at him as the person who help her escape the mengerie she was sold to. 
 Nina, a Heartrender grisha. Nina can control your blood, breathing, and stop your heart in your chest. To be honest she could probably do that with out her powers shes so amazing. Nina has come to Ketterdam trying to save a friend/foe but she was once in the Ravkin Army, looking for Grisha's all over the world to ask them to join them and build up Ravka since it was left in ruins from the war 5 years ago. 
 Matthias is a Fjerdans soldier, someone who is trained to capture Grisha and prosecute them for their evil ways. He has been raised to believe they are devils and that it's their gods will they be wiped from the earth for being un natural. 
 Jesper *Cue Hamilton's My Shot* Jesper's a sharp shooter and Kaz's second, he's always looking for a rush of danger whether it be in the gambling dens, fighting for his life, or flirting with anyone with a heart beat. 
 Wylan's a merchant's son, he grew up in luxury, servants at the ready. Left home to escape into the anonymity of Ketterdam, he's clever and quick, able to snap a bomb together in mere seconds and draw a detailed map from someones descriptions. Still to soft to be on the streets Kaz and the Crows accept him for his bravery, loyalty, and damn cuteness (oh that's just me with the cuteness? Well then.) 
 All six of these characters set out on an impossible mission, to rob the notorious ice court. They must pull off the biggest heists of their lives to receive 4 million kruge. Enough money to buy Inej her life back, to pay Jespers Gambling debts, for Kaz to add to his underground empire, Let's face it Nina, Mattious, and Wylan are there for other reasons that Kaz has controlled: Freedom. 
 "Six people, but a thousand ways this insane plan could go wrong." 
 The best cast of characters I have ever read, if your looking for banter, sassiness, crazy good world building, and a story that pulls you in from page one you've found it. Also if you don't read it someone will surly throw this at you and that will hurt so your better off just reading the book already!
