I'm not sure what happened to this series, but at least for this and the previous book, it really seems like Hambly is just stretching things out as far as possible. There'll be a sentence of dialog, then 3 paragraphs of random descriptions that have little to do with the point, do nothing to further the story, and are just repeating things from previous books. Look, Barbara, we get it...the Winterlands are a sucky place to live, Jenny has hot flashes and mixed feelings about motherhood, and John is super curious and very disorganized. We don't need a rehash of each character's bio and motivations every time they're on screen.
At least 30% of the story is told through dream sequences now, which is the ultimate bad writer's crutch, IMO. How does John know what's going on in that other city? He saw it in a dream. How does Jenny know something's stalking her kids? Yep, she dreamed it.
And frankly, Jenny's constantly shifting powers are super-annoying. Yesterday she had godlike "dragon-magic", today she can't light a match, tomorrow she'll be totally helpless...until she spends some time meditating and realizes there's yet more magic in her somewhere, even after we're told repeatedly that all magic was burned out of her the day before. And Morkeleb has become the ultimate Mary Sue, swooping in randomly at the last second to save everyone multiple times in every book. Wait, how does a 60-ft long dragon get into some of these places? Well, he's somehow mutated into some kind of uber-dragon now, who has the ability to shapeshift, including into human shape, at which time he's basically a carbon copy of Don Simon Ysidro from Hambly's vampire books, complete with the requisite sexual tension with the married female lead. *Yawn*. About the only super power he hasn't manifested yet is time travel, but I'm sure that's coming.
I feel like everything after the first book needs a serious edit job. Or better yet, Hambly should've just left well enough alone and kept "Dragonsbane" a standalone novel.
