What kept me from giving this more than 3 stars were my sheer frustration about Gin's behaviour when it came to Caine and all those fancy repetitions: 
 - "Then he handed me a thick towel. I lifted it to my face and breathed in. It smelled like the detective - clean and soapy. Mmm." 
 - "The rain had made it transparent too, and I could see the ropy muscles of his chest through the thin fabric. Mmm." 
 - "His lips crushed against mine, even as his tongue drove inside my mouth. Mmm." 
 And all this on just two pages. 
 It was painful to watch how Gin repeatedly threw herself at Caine even though she knew that she would only get disrespect and coldness from him afterwards. 
 And even though she knew that he despises her for what she is. A supposedly fearful, cold and self-possessed (former) assassin. 
 Where is your pride, Gin? 
 Where is your self-respect? 
 And where is your brain that should make you realize that it was all just physical attraction? 
 I almost ragequit the series because of this. 
 But I am glad I didn't. Because apart from the Caine part of the story, Gin really kicked ass and the writing was better than in the first book. 
 The plot was fast, action-packed and entertaining. 
 Parts of Gin's past were revealed and we got some more pieces of the puzzle that is her life. 
 That gave Gin much more depth and I can't wait to find out more about her. 
 The Deveraux sisters were a fun asset to the world, there were mean, evil villains, and my favorite side character had to be Finn, who always managed to make me smile with the weirdest scenes and dialogues. 
 "Finn?" I asked. "Yeah?" "Did you bring your laptop with you?" He sniffed. "Do I ever leave home without it?" Question asked and answered. 
 Sometimes I wondered how Finn pulled himself away from his computer long enough to chase after anything that had boobs. 
 Another thing that bothered me a little was the excessive hand-holding. I often figured out things before the protagonist did, and there were needless repetitions of character descriptions etc. 
 All in all, this was a pretty entertaining read though and I will continue the series.
