When I first heard the premise of this book, I have to be honest and I did think... "another one?". For the first time in my life, I am so glad to say how WRONG I was. The author starts the book by educating you - in depth - on the key characters. By creating a in depth understanding of these characters early, what makes them tick, what their motivations are - truly helps create a base for the rest of the book and how the players are connected. The level of detail and specificity of the author's writing, is in one word - intense. I thoroughly enjoyed taking my time, re-reading where needed, to make sure I captured every single thought and intention. The author pulled from real life - and you can tell she researched every tiny fragment to ensure accuracy - and this makes it all seem so much more real. I found myself, throughout the entire book, wondering "Oh my gosh, is this really real? Is this group out there? How do I sign up?" - and yes, looking for "X'ers" everywhere I go. Knowing that this is a two-part (maybe more??? please?) series, when I finished the book, I went back and read it - all over again - to make sure I did not miss a crucial detail that would lead into the next book (and I had)."They" say first time authors either get it or they don't. This author gets it. Hands down. I for one cannot wait to get my hands on the second book, and anything else the author dares to share.My recommendation: Buy this book - Give it to all of your friends - Read it (and read it again).
