I may read the next Updraft book because I am a sucker for flying and also, it looked at the very end like they were laying hints that the next book will actually start explaining the bone towers and stuff. But yeah, plot was super-ya-formulaic and characterization was not great. (I read it after the nebula noms and I was like '...why this, it's interesting, but it is not standout, also why does nobody have enough siblings' and then I saw it came out of Viable Paradise and was like, oh, that explains why all the sfwa writers have read it.)

On the other hand I might just finally acquire myself all three books of Zilpha Keatley Snyder's Greensky instead.
