The way of shadows chapters 3-7

I got really into the book after I read these Chapters because Azoth wants to be an apprentice of Blint who is a wet boy. Blint tells him no but later that night Blint kills the duke's wife and hears about the war and also Rat figures out what Azoth is trying to do so he starts punishing him. Later Azoth sneaks off and it in a alley way and kills a rat and then Blint shows up and says if he kills his Rat then he will be his apprentice.
