I always fear the second book in a series, because I don't expect much from it. Something has to happen between the beginning and the end, and we're stuck with a whole lot of rising action and not much plot. 
 That was a really long paragraph just to say, "this doesn't happen." 
 We're still trying to track down the Magister, but it's not as easy as it may seem--the bothersome Benedict Lightwood wants the Institute for himself, and proposes that Charlotte track down the Magister in a fortnight otherwise she will not be fit to head the Institute. And for some unknown reason, the Council agrees to this plan. 
 Luckily, Charlotte has a loyal band of Shadowhunters behind her--plus an array of Downworlders and household servants. And at the core of it, naturally, are Tessa and the parabatai duo, the irresistible Will & Jem. There's drama and secrets and declarations of love everywhere, and not just between these three. 
 (If you follow my blog you know how I feel about Jem, and I may have gushed over him in my Clockwork Angel review. So I won't bore you with that again, even if it's really really hard to contain myself.) 
 And now... to wait on book three. 
 Also: (view spoiler)[If Tessa does anything to hurt Jem in the next book I will hurl it across the room. Don't doubt me. 
 Oh, I said I wouldn't mention him, didn't I? (hide spoiler)]
