If you ever wondered whats it like to be suddenly put under the Witness Protection Program, look no further than this book. This book amazed me from start to finish. Why? It has great technique in the writing style that you felt like you were on the run. My heart raced as I read this book. I felt emotions, just like the character. And even after finished reading the book, I think I might change my appearance! LOLWhat I liked most about this book is the writing style. Ms. Shaw did an absolutely great job in hooking the reader from the very first line. What's even better is that she kept me on my toes, thinking to ever bit that I had read,"What did this girl witness?" Even as the reader, you are left clueless as to what she saw. The main character, Liza, is pulled from the life she knows and into a life of running. She must drop everything. School, friends, relatives, phones, her appearance down to what she orders to eat, had to be change.I loved the mystery of this book. As I continued to read, I thought I be able to crack what really happen. Liza herself, didn't even know what she saw till it came together in the end. I was in shock and thought, Wow. Such a small incident, in which she didn't even realize what is going on, change her entire life. You need to read this book. I can't express enough how much I looked over my shoulder and even had to takes breaks. My heart broke for Liza. So much change, in so little time. Amazing writing, amazing characters and one heck of a story line, Tunnel Vision is my favorite book this year. I have never been so taken back and surprised by a book. Simply fantastic!
