Personally, I'm rooting for Kaz and Inej :)
I want to say Kaz and Inej but I'll wait until I finish the book or I'll jinx it.
I've already finished the book, but I love the way Bardugo handled Kaz and Inej. I think it's one of the reasons Six of Crows is my favorite book of this year (so far).
What do you think?
