Silverthorn. Moonveil Chronicles, #1

At Moonveil College, magic is power. Love is treason. Cassian Vale was never supposed to belong among Moonveil's noble heirs. He arrives from a poor harbor town with a scholarship, a worn coat, and no powerful family name to protect him. But during the academy's magical selection, Cassian does the impossible: two ancient Lines answer his call. Then he meets Evander Silverthorn. Cold, brilliant, and dangerously powerful, Evander is everything Cassian despises-the untouchable heir to one of Moonveil's greatest houses.
They should be enemies. Instead, their magic recognizes something neither of them understands. A touch can shatter wards. A duel becomes something far more intimate. Dreams begin pulling them toward a forgotten kingdom, and buried records suggest the connection between them began long before either of them was born. Because Moonveil has secrets. So does House Silverthorn. And something ancient beneath the academy has started to wake.
As rivalry turns into forbidden desire, Cassian and Evander must uncover what destroyed the bonded wielders who came before them-before history decides to repeat itself.
