Feared by every pack but cherished by her own, Alpha Carley carries an ancient secret—Fenrir, the legendary wolf no one can defeat. Bound by duty, she travels to the Alpha Summit, where she meets Ryker Blackwood, a powerful young Alpha forbidden to claim a mate until his twenty-first year. From the instant their wolves recognize one another, fate begins weaving a bond neither can deny. As rival packs hunt Carley for the power she possesses and an ancient prophecy awakens, they must choose between the laws of the kingdom and the pull of destiny. Their love could unite every pack… or destroy them all.
