There is an overuse of the word estrus in this book.Apparently it wasn't memorable enough the first two, three or four times so it needed to be bandied around a bit more.I think the author needs take a closer look at shifter and pack law. Yes, it is fiction and there are always ways and means of bending the rules, but if half the story hangs on the rules within the pack then they need to be adhered to a tad more.Frankie is one weak derriere of an Alpha. She is not only led by her auspicious estrus, which she also uses as an excuse at every turn, she also acts like a lone wolf and not a leader of a pack.Packmasters don't just up and leave their pack at a whim and they should also command respect from their pack. Then again Frankie was way too busy either being naked, crying in the corner or banging strange half-breeds to master any pack.Jace also needs to work on his too hot to handle pick up lines when he is overcome by the infamous estrus of said naked wolf. Downright insulting, but then again perhaps he was just overcome by the size of his own gigantic manhood. Blood, brain and gravity.Overall it was an ok read that could be a good one if more attention is paid to supernatural etiquette.I received a copy of this book via NetGalley.
