I loved the first one. Sanderson's pacing is excellent - I was expecting a slow burn based on what I'd heard about them, but I don't think that's the right phrase. More like a fire getting constantly stoked until something has to explode.
Right up until the "Sanderlanche" when it all falls into place!
My husband has finished listening to or reading everything that has been released in the Cosmere; one of my children has read almost all of the books; I am right in the middle of Stormlight Archives!
I really love these books! Up until my kid moved out, we would sit around and talk about the Cosmere (except I was so far behind that they would have hours more chatting without me, because we are a spoiler-free family - as much as possible, at least)
So far, I have loved every book (listening to the Graphic Audio version) and will be sad when they end. Maybe the next Stormlight Archives book will be out by the time I get that far!
