I read Flewelling's Nightrunner trilogy (on its way to a quintet now, I see) ten years ago, and found it a somewhat awkward mixture of intriguing plots with shaky world building. There's some of that here, but I definitely find it an improvement on her earlier work. The sections with Tobin in particular drew me; he's one of the most "real" children I've read in the "heir to the Kingdom grows up in hiding before reclaiming his destiny" sub-genre. The bits with the wizards seemed bland and generic in contrast, though they improved towards the end. I'll be picking up the next book in the trilogy.
