The Wicked and the Just by J. Anderson Coats (Published by Harcourt, April 17, 2012)
Cecily longs to return to her beloved Edgeley Hall, where her father was lord of the manor. But now he has completely ruined her life. He is moving them to Caernarvon, in occupied Wales, where he can get a place for almost nothing, since the king needs good strong Englishmen to keep down the vicious Welshmen. At least Cecily will get to be the lady of the house at last—if all goes well.
Gwenhwyfar knows all about that house. Once she dreamed of being the lady there herself, until the English came and destroyed the lives of everyone she knows. Now Gwenhwyfar must wait hand and foot on this bratty English girl who has taken what should have been hers.
While Cecily struggles to find her place amongst the snobby English landowners, Gwenhwyfar struggles just to survive. And meanwhile the Welsh are not as conquered as they seem. Outside the city walls of Caernarvon, tensions are rising ever higher—until finally they must reach the breaking point.
I love YA historical fiction with unique settings and so I can't wait to read this book, I don't think I've read any books set in this place/time before.
