I read D-Nine in exchange for honest review from Tomoson. The book was written by Magnus Tor. The book is currently free on Smashwords.
About the book:
What if you wake up one day and found out that you are of the opposite gender?
James is suffering from bouts of headache and the latest one gives him an experience of a life-time. He gets to become a girl but it comes with a price, his or rather her life is in constant danger as assassins hunt after her. He needs to find out who is behind this before his and her life becomes forfeited. In the midst of adventure he also needs to face with another difficult situation, love from another guy. Will he survives the conspiracy or death is a welcome solution to his forbidden love.
