Signed Bound by Runes (The Cursed Runes Series Book 1)- Katherine Scheirer

Lilith never expected to be anything other than ordinary. She planned to follow her brothers' path to Ardaven Academy, train her magic, and live a quiet life. But when a prophecy entwines her destiny with the destruction of her kingdom, most of her powers are bound by an ancient rune curse.

Hiding from the lord who cursed her, she is sent to Skilheim, a brutal, magical college where only the strong survive. There, she feels drawn to her mysterious mentor, who offers her a bargain, one that may challenge her providence.
