Warrior Born - The Katana Series, #1

When the God of War wants you dead, there are few places to hide. Connor MacDonald doesn't know of the bargain struck between her parents and the Gods nearly 200 years ago in the Highlands of Scotland, sealing her fate as Daughter of the Sword. But when Bishamon, the Japanese God of War, decides to create the final battle of the mortal realm, the gods from all beliefs are called upon to stop him at any cost - before he seeks revenge upon Connor and those she holds dear.
When faced with the truth about her past, Connor is thrust into a deadly game where she is a pawn, forced to obey the whims of the deities who watch her every move. Endowed with the spirit of the Ancient Celts and the skill of the immortal Samurai, Connor must become one with her katana and embrace the will of the Gods if she is not only to survive, but kill Bishamon before he can wreak havoc on the past, the present and the future of mankind.
