I kinda suspect that I'll be the same - I love heists which is why I bought Six of Crows when it was on a daily deal a while back! (And my favs on the show are, indeed, Inej, Zaj, and Jesper.)

I mostly just want to read the main series for mythology/background detail as incredibly nerdy as that is. I'd say my odds of bouncing of for those are higher than the crows books though, if only because I've read a lot more of that type of story. (Why aren't there more magical heist books though, that's the real question.)
