Intense is my word for this book. Six is such an interesting and intense character he seems like he never has a off button. He goes full force into everything he does. Lou is just as intense but in the lab where she is along and working on solving these complex probelms. The writing is so great, it just draws you into this story and the lives of these characters and doesn't let up. There is sexual tension and action and drama plus hiding out from the bad guy and seeing Lou develop and transform into this gun shooting, protect her man, this lady it is just awesome! So many great things about this book!

Louisa has a few social hold ups. However she overcomes them pretty fast around Six and his friends. Louisa is also really smart, but Six doesn't have much trouble keeping up with her. She is really good at explaining things so people can understand.
Six knows at their first meeting that Louisa is someone special. So when a second chance comes his way, he jumps at trying to get to know her. Not knowing that her life was in danger. But hey, that's what he specializes in.
Under Fire, is full of suspense and kept me turning the pages quickly.

I absolutely love Scarlett Cole's writing! Ever since I read her Second Circle series I've been hooked! This book is no different. New series, new set of characters, but the same writing style that makes me absolutely love this book! I loved Six and Lou so so much. One thing I loved the most about them is that they just "got" one another. They didn't ask questions or wonder why the person was the way they are, they just accepted and moved on. To me, that was so refreshing. This book was fast paced and kept me turning pages and on the edge of my seat! A brilliant way to start a series that I can't wait to get my hands on the rest! 5 stars!!
