I thought that the first book was full of action and drama! This second book makes the first look like the characters were living in Disneyland! 
 Thornhill picks up right where Hemlock left off. Jason & Mac are out searching for Kyle and they are going to try to convince him to come home. Jason is a bit out of sorts and is really starting to become an alcoholic. Mac is unsure whether he will help or hinder her so she calls in reinforcements....Serina! She figures that she will see if Serina can help just for a few days then if they have no luck, she would send Serina & Jason both back home on a bus and continue her search on her own. Little did she know that there were other plans in store for all of them and they find themselves behind enemy lines in an actual camp!!! 
 I really enjoyed Mac in this book, she was stronger than ever trying to think of any way possible to help her friends by putting herself in danger many times. We also get a few new characters which I enjoyed just as much as the others. It put a whole new spin on the story itself. 
 I also enjoyed the sort of love triangle going on between Mac, Jason & Kyle. I honestly am not sure which one I would like to see Mac settle with. I know her heart is with Kyle but there is just something about Jason that I truly love! The ending leaves us with a terrible twist that may just decide the trios fate for them. We shall see!!! 
 Waiting patiently for the next book *taps nails on the table*!
