External Forces: The Laws of Motion, Lex I by: Deborah Rix

It's 100 years since the Genetic Integrity Act was passed and America's borders were closed to prevent genetic contamination. Only the enemy, dysgenic Deviants, remain beyond the heavily guarded border. The Department of Evolution carefully guides the creation of each generation and deviations from the divine plan are not permitted.

When 16-year-old Jess begins to show signs of deviance she enlists in the Special Forces, with her best friend Jay, in a desperate bid to evade detection by the Devotees. Jess is good with data, not so good with a knife. When the handsome and mysterious Sergeant Matt Anderson selects her for his Black Ops squad, Jess is determined to figure out why. 

As her deviance continues to change her, Jess is forced to decide who to trust with her deadly secret, because if the enemy doesn't kill her first, the army will. In the maelstrom of first kisses and first kills, treason, betrayal, and heartbreak, Jess must discover what's actually out there, in the Deviant wasteland over the border, if she has any hope of making it to her 17th birthday.

Review:
External Forces: The Laws of Motion, Lex I by: Deborah Rix 

External Forces is a rollercoaster throughout the book. Ups and downs, fast and slow pacing. The more you read into the book the more I felt and understood the characters. Jess would have to be one of my favorites in this book. She wakes up with a dark mark, meaning she is a deviant! Deviant is someone who is usually killed when exposed. This book follows Jess and the world she lives in. The book is one that kept me reading throughout the pages, even with I felt the book was at a slow pace but is was because a fast pace was coming. There is a lot in this story, love, action, and cliffhanger! Yes, there is one of those! It's a book that science fiction fans will like!
