3.5 or possibly a 4... 
 This one was a bit of a roller coaster, some parts I liked and others not so much. 
 The romance in this was a bit all over the place. At the start I thought the chemistry seemed way too instant, but then the characters were cold again towards each other and then one we find out that is in love with the other. It was a very cold/hot relationship, so much so that it made it a little hard to see the progression of it. Despite this there were still awesome agnst scenes between the two lovebirds, ones that I thoroughlly enjoyed. 
 Still a really good read overall.... it really hooked me about half way through and that's when I couldn't put the book down. (I read this one in a few sittings you see) 
 Anyways, good summer read :D
