It’s 1558, and warlords across Japan are battling for territory and control. Into this setting, award-winning author Tanya Lloyd Kyi weaves the stories of three people: Mochizuki Chiyome, a young woman determined to become a ninja whose plans are thwarted by an arranged marriage; Takeda Shingen (The Tiger), a fierce warlord seeking a new weapon to outsmart his enemies; and Aki, an orphaned tavern girl whose destiny is changed by a mysterious woman. As their stories intersect, the three characters become key players in an elaborate network of undercover female ninjas who will eventually shift the balance of power in Japan.
