A different read that blew my mind, I totally love it!The plot of the book is what got me hooked. Several boys living in a locked facility being tested on, secret government meetings, and a curious young girl who is not who she think she is...yup, loved it. Each chapter, the reader learn more and more about the secret facility, leading the reader to a breakout and the unloading of heavy burdens. For a moment while reading this, I had to catch my breath!The love interest is good but it did bother me a bit. For some reason (I'm sure it if is me) ALSO: SPOILER AHEAD ---> I'm bothered by the prospects of a boy falling in one with one sister and then the other. Is that weird? I mean, the love triangle in general already sets off the tone for me and then this??? Anyways, other than that, the love interest is what I thought. Lots of lies, torn hearts and of course lots of decisions to be made. I'm not sure how this love interest will go and I'm very interested in seeing where it develops.The other element I love about this story is the learning the back round history of the characters. Much of their memories have been lost. Learning about who they really are and what they done in the past, perks my interest even more. I want to know everything from the beginning. I want to know everything of who they are and why they were chosen. Yes, I need the next book.Altered is a fantastic book! Laced with much action and loads of secrets, this is a great ride to be on if you love the types of stories that hold more that what you know. Yearning to read the next book, Altered is awesome!
