Finished the Gathering -- realized I was about 80% through the book when nothing major had happened yet -- she made up for it in the last 20%. Lots happened. I'm going to have to take this back -- even though she spends way too much time explaining things away that are only confusing because she introduced the idea, and there are characters that seem a little too deus ex machina for my tastes -- well, not so much deus ex machina, but ... they only seem to be there as a writing device -- I.E. Warren -- knows stuff when it needs confirming, but doesn't tell it until it's figured out by the protagonist, so it's not written from a omniscient point of view.
That said -- strangely compelling. There's a lot to like about her. The whole second entry into Midheaven thing -- superb. Builds up this confidence going in, and ... doesn't spell out the deflation, but lets the actions speak for themselves.
So yeah, I'll keep reading her.
