I remember, when the announcement was made that Robert Jordan would be expanding his Legends short story into a novella or so, how irritated The People were by this distraction from an already quite expansive and never-ending main story. And it certainly seemed like a fair cop. I remember that I liked it the first time I read it, if nothing much else beyond that, but I have definitely learned something useful about New Spring on this, my second time reading the book. (Which, not to beat a dead horse, would have probably been harder to spot if this were not a consecutive read-through of the entire series.)
First, though, I’ll point out what I remember from the subsequent book, Knife of Dreams. It is that I liked it a surprising amount the first time through, far more than I’d liked any of them the first time in years (excepting only the climax of Winter’s Heart.) Given that factor, I can now praise NS highly indeed, because this is the book where Jordan remembered that his series can be focused on exciting events and spread itself out over significant spans of time at the same time as worrying about politics and natural consequences of previous events. And the payoff since has been nothing short of spectacular. ….except for the part with the amyloidosis. That part sucked.
But yeah, every part is good. Tower life, Black Ajah, a desperate quest, the Aes Sedai testing ceremony, Elaida’s tragic fall from humanity into caricature, swordplay… it was the first wholly exciting book in such a long time, and even better, it wasn’t the last. I guess this is evidence not to complain about a writer’s process when you are waiting for a book to come out and the author isn’t writing it?
 Which, lucky you, you didn’t have to wait until my ongoing reread of KoD is completed for me to know about it even though I know almost nothing about what will happen in the book, thanks to this website right here.
