The Magicians' Guild - Trudi Canavan
This was something of a disappointment. The blurb sounded very promising - citywide purges by a mysterious guild of magicians, rebellion from the streets - but the book itself turned out to be rather wet. The author's just too damn nice about everything - yes, the magicians purge the city, but they don't actually kill anyone (except by accident), they just push them out through the gates. Yes, the guild is trying to hunt down the rogue magician, but only so they can help her. Yes, there's a bad guy with a wicked plan, but it's actually not very wicked at all, just a bit petty and snobbish.
Canavan also has an annoying habit of making up words for things that already have names, thankyouverymuch (a "bolhouse"? Oh, it's just a pub, where they drink "bol"). If it's a spider, then call it a bloody spider. Made-up words rarely add anything to a story, and they're usually just slightly irritating.
To be fair, I did manage to finish the book, and if you're a teenager you may well enjoy it, but it doesn't have a lot to offer an older audience. I won't be reading any more of hers unless she gets considerably nastier.
