A pretty strong second installment... I'm always a little wary of YA trilogies, because it is so so so easy for the second book to be nothing more than exposition/set-up for the 3rd book, but thankfully that was not the case for this one! It had enough action and character growth to stand up for itself, I think. Reserving judgement of the series as a whole until after I've read the third book, but so far so good.
