Witchlanders by Lena Coakley

High in their mountain covens, red witches pray to the Goddess, protecting the Witchlands by throwing the bones and foretelling the future. It’s all a fake.
At least, that’s what Ryder thinks. He doubts the witches really deserve their tithes—one quarter of all the crops his village can produce. And even if they can predict the future, what danger is there to foretell, now that his people’s old enemy, the Baen, has been defeated?
But when a terrifying new magic threatens both his village and the coven, Ryder must confront the beautiful and silent witch who holds all the secrets. Everything he’s ever believed about witches, the Baen, magic and about himself will change, when he discovers that the prophecies he’s always scorned—
Are about him.

Translation for my romanian readers:

Sus, in adapostul lor din munti, vrajitoarele rosii se roaga Zeitei pentru protejarea tinutului Witchland, ghicind viitorul in oase.
Totul este o pacaleala.
Cel putin asa crede Ryder. Se indoieste ca ele chiar merita ofrandele pe care le primesc - un sfert din toate culturile pe care le produce satul. Si chiar daca ar putea prezice viitorul, ce pericol ii mai poate astepta acum, cand vechiul dusman al poporului lui, Baen, a fost infrant?
Dar cand o magie noua, cutremuratoare ameninta atat satul cat si vrajitoarele, Ryder trebuie sa consulte frumoasa si tacuta vrajitoare care detine toate secretele. Tot ce a crezut despre vrajitoare, Baen, magie si despre propria persoana se va schimba, cand descopera ca proferiile pe care le-a nesocotit mereu sunt despre el.
