Blades and Feathers by Kate Grove

A stolen treasure. A desire to be recognized. And a dangerous time to live in.

Whoever returns the stolen Jewel to the tengu clan, will be recognized as the next leader. This is the perfect chance for Yoriko to gain her family's affection, and she throws herself into the mission immediately, disguising herself as a man.

She didn't plan on working as an aide to a greenhorn lord in the process but she's certain the Jewel is somewhere in his castle and Yoriko is determined to find it. As she watches Takeru deal with the aftermath of the war that left his new territory in shambles, she admires his tenacity and dedication to his people.

Unexpectedly drawn to him, Yoriko soon realizes that there may be a place that accepts her as she is, without pretense and bribes - and it isn't the tengu compound. While secrets threaten to keep them apart, she forgets one thing.

The Jewel has attracted others, far more dangerous and ruthless than Yoriko.

In order to protect him, Yoriko must betray the trust of the only good man in her life. Will they find their way back to each other? Can their love survive her betrayal?

Blades and Feathers is the third book in the Yokai Treasures series, a fantasy romance set in sengoku jidai (16th century Japan).
