Probably unsurprising to say I thought it very overhyped (with *this* much hype it's hard to live up to it.) 
It's a fun, diverting, fast-paced read but overall feels a bit like the grocery-store brand version of a much better book (though which one, I'm not sure about) 
There were some good moments, and the way the heist goes down is very satisfying.
I thought everything in the world- and character building felt a bit shallow
The characters all get their tragic backstory, but don't feel very distinct or very real
The world-building has much potential, but again seems a bit half-hearted
The magic system in particular, I didn't like. The rules are unclear and doing magic doesn't seem to exact a price, which is not my favourite
