Thorn & Needle : History of The Sister Book One

Ayanami Hesakyu, the only child of a feudal lord has had a pretty quiet life. Other than the prospect of being made to marry soon, and to her parent's advantage, she never had much to complain about in her 18 years.
That is, until she woke up this morning bound and gagged, chained to the wall of a tiny wood hovel somewhere in the woods. Suddenly she has plenty of things to complain about, and reason to miss her gilded cage of traditions and her parents expectations.

At 17, Michael Korsky has already been through a lot. Losing his mother, he had run away from his two violent older brothers. He survived in the wild for five years before something happened that made him return, and submit to their fists.
Now Misha has to decide what having a roof instead of a briar over his head is worth. And whether he'll simply run away again, or try to help the girl his brother's kidnapped. That is, if he even can.
