For the most part I liked the book, didn't love the twist ending tg be part of it is because the character it dealt with didn't care for her either not that the other character was oblivious to it. Now the book could have been better there was some parts that just had big errors. If only the author did just a little bit of research and it would have been better. But I know what is going on here. The author who isn't a terrible writter had two top seller books and this one? Was written a little to fast so it could come out on the coat tails of the first two books. He should have taken a little bit more time to flesh it out more.
One more thing that can be spoilerish so don't read if you are going to read the book though I figured it out right when it happened. Anyways here comes a spoiler turn away before its to late! The main character Daniel is an app maker and was stupid enough to open an email from his x girlfriend which was obviously not from her and put s virus on his computer. Now come on if you are a computer techie your not going to click the obvious virus emails seriously why put that kind of stuff drives me crazy!! Ok *takes deep breath* better now. It wasn't a horrible book it kept me interested and parts of it I had a hard time figuring out but others like the twist at the end just annoyed me. From other reviews I have read Mark Edwards first two books are much better then this one so those would probably be the safer bet over this book.
