 The concept of Uninvited is a really interesting one. Imagine taking a test that will determine whether or not you are a killer. It's scary enough thinking you could be capable of doing such a thing, but if you're tested positive, you WILL become a killer at some point in your life. In the case of Davy Hamilton, an upper-class music prodigy, this is exactly what happens. After being tested positive for Homicidal Tendency Syndrome, she kisses everything she ever knew goodbye. Her family, friends, scholarship, all gone in the blink of an eye. She's taken away from her home and forced to live amongst other HTS carriers like her. 
 Overall, I had a really fun time with this book. There was a good mix of actions and suspense, and a touch of romance to boot. It really sucked seeing Davy's life pulled out from under her so suddenly. Her (ex)best friend and (ex)boyfriend turn on her so suddenly and were horrible people. Honestly, I'm glad they're out of her life because I hated them with a passion. Luckily, she becomes acquainted with fellow carriers Sean and Gil. They give her some hope to cling to and help her with her abrupt life transition. 
 I really liked Davy's relationship with Sean. While they do have a bit of romance, I appreciated how they started out as companions-turned-friends. He basically takes her under his wing, showing her the ropes and protecting her in some sticky situations. He gave Davy someone to relate to in a time when she felt truly alone. My only quibble is that I thought he saved her a little too much. He always seemed to be there when she needed help and it would've been nice to see her save herself more often. 
 There were a couple things I had slight problems with. Firstly, more world building would've been great. Several places are mentioned to be overrun with crime but I wanted to know more about what was going on elsewhere. Secondly, we barely get to know anything about Sean. I mean I'm pretty sure it hasn't even been mentioned how he got imprinted, which was a big focus of Davy's for a while. Lastly, the final action scenes of the book were pretty anticlimactic. I expected more going up against Jackson and Addy. 
 Other than some issues that can easily be fixed in the sequel, I really enjoyed Uninvited. It's a thrill ride but also brings up some really interesting topics about human nature and the potential of humans. Can't wait for the sequel!
