Uninvited (uninvited #1) by Sofie Jordan
Book Blurb (from goodreads):
When Davy Hamilton's tests come back positive for Homicidal Tendency Syndrome (HTS)-aka the kill gene-she loses everything. Her boyfriend ditches her, her parents are scared of her, and she can forget about her bright future at Juilliard. Davy doesn't feel any different, but genes don't lie. One day she will kill someone.
Only Sean, a fellow HTS carrier, can relate to her new life. Davy wants to trust him; maybe he's not as dangerous as he seems. Or maybe Davy is just as deadly.
This is by far one of my favourite books this year. The way how this book is written makes me really feel for Davey and what she is going through even though i cant really relate to anything that she has gone through. I wish that Sophie had said a little more on what the brother usually does because at the beginning of the book when the mum called Davey she automatically thought that her brother had done something again. I don't get Sean though. How he told her to not trust anyone and then to tell her to trust him. He is so confusing maybe that is why he was one of my favourite characters. I would recommend this book to anyone that loves action and very confusing romance.
