Update: still annoyed with Harmony, but it's different this time. I'm less upset and more indifferent (I do understand his logic, and I definitely agree with hos logic, but he still interferes too much for a God who says he won't).
On a different note, this has been the best book in Era 2 in my opinion and here's a list of why:
Wayne letting go of Ranette (and asking inappropriate questions while doing so)
Marasi walking into Wax and Steris passionately competing over house ledgers
Wayne and MeLaan being cheeky on the train while the rest of the train is being ROBBED
Marasi being jealous of said cheekiness
Hoid being Hoid
Khriss being Khriss
Wax going from lawkeeper to outlaw
Wayne old shaming Wax
Wayne in general (I NEED him to become a worldhopper, imagine all the mischief)
Hints of the civilisations outside Elendel and the Basin
All their advanced technology
Kelsier being Kelsier
Allik calling Marasi the cute one and Wax the Metabolic One (etc, etc)
Wayne again (he may be my favourite ever)
Wayne and MeLaan
Badass Wayne
Both Marasi and Wax not letting the power of the Bands of Mourning consume them
A darker side of Wax?
Marasi and Allik
Wax and Steris
I also desperately want the fourth book. I am the most excited to find out more about the interaction with the outside cultures.
