Full spoiler-free review about this and White hot can be found here 
 Maybe one of the best first in series that I have ever read. Solid book, no flaws, amazing banter, very mind-gripping action scenes and steamy, steamy attraction. 
 If you have not read this, get it at once! 
 I have read this so many times in a year I cannot ever remember them all. 
 5 billion stars.
