When a mysterious summons offers her an opportunity to leave her stifling life behind and go on an unusual adventure, Charlie of Windsong is too curious to say no.

Charlie learns that not only has she been chosen to revive a league of exceptional women called the Order of the Dagger, but that her success in doing so might be instrumental in stopping a war. Her decision to leave her family and the comforts of home behind means learning to take care of herself while she travels through a country adversarial to her own. While she's busy navigating danger from both mundane and magical sources, she finds herself saddled with an unwanted companion who is a little too curious about who she is and where she's from.
A decision born out of a restless desire for adventure will start her on a journey that will change all of the Eastern Lands as it tests the limits of her courage, ingenuity, and determination. Far from her sheltered and privileged life and growing to enjoy her independence, Charlie begins to consider her purpose and her place in a world much bigger and more complicated than she ever imagined.
