I always love time travelling romance. But the genre is starting to get too stale. Somehow the book is too much like Crichton's Timeline and I immediately got sucked into it. 
 Its a combinition of The Borgias and Fringe in some way. Face paced, never detract from the points, filled with swordfight and medieval medicine. The girls are very independent although somewhat vulnerable. Its a good book to distract from the vampire YAs, recommendable for those who are tired of the threesomes romances and love action.
