First if you haven't read Gypsy, the first book in the Cavy series, STOP now! Really stop, and read that one first, so A) I don't mistakenly spoil anything for you, although I don't think I will, but B) It is a great book too and you might not understand what I am talking about if you haven't read the first book.
Ok, now that we have that taken care of, Alliance, the second book in the Cavy series, picks up right where Gypsy left off and is even more action packed and exciting than the first book, if that is even possible. All your favorite, and not so favorite characters are back with Gypsy of course at the center of it all.
The Cavy are with the Olders, but are not so sure that is the best choice for them, along with the drug, GRH-18 they are being given. Even though the drug seems to help them control their gifts, why won't the Olders tell what it is and why won't they tell them they really have Flicker in a coma upstairs, instead of planting a impostor (spy) with them? It seems everyone wants to use them and they don't know who to trust except themselves. So when they find one Older who really will help them with Flicker, they run, with only slight trepidation for their friend Flicker. Only to find themselves back with the CIA and Dane Lee, trying to help save the world from a mind scrambling computer virus. But when a new twist is thrown into the mix and things get intense we will see who comes out on top.
These characters mesh together so well, it seems they have been together forever, which I suppose in some respects they have. They still act like teens in most respects even though they have these special capabilities and always need to be one step ahead of everyone else. The whole story is put together in a way you just are sucked in and can't get out of it is just to exciting.
For a sequel this book does not disappoint, if anything it is better than the first and only promises a better third book. You will be on the edge of your seat the whole time and clamoring for more! You just can't put this book down so prepare for some, please do not disturb reading in progress, time.
