Too many povs and nothing really happened?

There was no need to constantly switch povs and half of them were for pointless chapters that mean nothing and all they do is over explain something that anyone even half paying attention could have learned. (Like yes, the tithing for the bone shard is bad we understand it, you don't need to give us an entire character arc and saying it 5 separate ways to understand it. If it was good the people wouldn't try to keep their kids from it. Obviously.) Also the constant switching of povs was confusing and made the story feel bulky and uncoordinated.

At least 100 pages should have been cut to keep this from dragging on as much as it did.

Phalue and Ranami's chapters could have been cut and nothing would be lost, and it would have made the story slightly more linear. There was at least one seemingly major plot thread with Sand's pov that never goes anywhere and the only connection we have to it is in the opposite direction.

I want to give the second book a chance as this one was a LOT of background/attempt at world building and hopefully after this the next one won't drag as much and will actually have a plot.

For a book called The Bone Shard Daughter, Lin is hardly in the story and when she is she's not doing anything interesting or important, instead just doing the same thing she was the last time we had a chapter for her.
