Ex Input:
This was not good. Too many plot holes and too little character development. Also a lot of grammar errors such as missing words or wrong word usage. I finished it but only cause I just wanted to see if they ever found the girl that got away. If there's another book in this series I'll read it. There were enough questions left unresolved at this point so perhaps more will be revealed. All in all, an ok read. It does have potential... maybe it'll get better as time goes on.
