Risuko

Can One Girl Win A War?



Tenth Anniversary Edition — with new author essays on the history behind the
series




In the chaos of Japan's century-long civil war, young Risuko is sold to the
legendary Lady Chiyome and taken to a remote mountain school. There she's
trained alongside other girls in skills no one will explain — cooking,
dancing, spying — for a purpose she's not meant to understand. But Risuko is
a climber. She goes where she's not supposed to go. And what she discovers
will thrust her into the heart of a conflict that could reshape a nation.

Samurai, assassins, warlords — and a girl who likes to climb




It's 1570. Kano Murasaki — called Risuko ("Squirrel") — is a fatherless girl
living in a ruined village, more comfortable in the treetops than on the
ground. When the enigmatic Lady Chiyome purchases her from her desperate
mother, Risuko is carried across a war-ravaged landscape to a mountain
compound called the Full Moon.



There, she and two other recruits are trained by kunoichi — spies,
bodyguards, assassins — in an education disguised as domestic service.
Kitchen work becomes blade training. Dance becomes combat. And the women
around her are far more dangerous than they appear.



But someone at the Full Moon is hiding a secret. When betrayal strikes at
the heart of the compound, Risuko must decide what she's willing to become —
and what she's willing to do — to protect the people she's come to love.



Risuko is the first book in Seasons of the Sword, a complete, award-winning,
four-book series set during Japan's turbulent Sengoku period. Rich in
historical detail, sharp with political intrigue, and driven by a heroine
who keeps climbing higher than anyone expects.
