this was an interesting book. we meet Ari who we learn is part human part extra terrestrial. we find out that she is hiding from GTX, the lab that created her. she has rules that she needs to follow to get by, but slowly events happen and one by one those rules are slowly broken. 
 i enjoyed this book because we had a good background of what Ari went through at the labs through flashbacks. it was also an easy read without getting to scientific. plus as always a nice love twist to it.
