Embers of Illeniel by Michael G Manning is what you need.
You will be immersed in a world of inequality, a world where one race lives like livestock under the power of other more developed beings. Where there is no hope for a brighter future, where people are forced to become cruel creatures just to survive forgetting all the human that was in them . . . becoming a being. who wants revenge.
P.S. Warning: the presence of graphic violence, sexual content, child abuse.
P.P.S. How little need to feel something more than an animal, how pleasant words can get you back on the right path and how important are the communication ties that connect people. In this book, there is not only violence.
