In this epic historical saga reminiscent of Game of Thrones meets Memoirs of a Geisha, two very different women find their fates intertwined. At the dawn of the shogun era, in 12th century Japan, Tomoe is strong but obedient, a beautiful onnabugeisha (woman who studies the art of war), the concubine and army captain to the reckless orphan Yoshinaka, whose vow to avenge his father’s death and oust his cousin from power takes over their lives. Yamabuki is the sheltered, shy noble sold off to become rough Yoshinaka's legal wife, sent to live in the remote mountains of Japan, where her scornful lady-in-waiting is none other than the warrior woman Tomoe. As the epic Gempei War begins and the women prepare for battles both literal and of the heart, losing means death, but victory might mean losing everything.
