Tempest by Anna Hackett

One of five brothers granted the power of the wind, Lorenzo Venti is Keeper of the Winds. A loner at heart, he’s fine that his duty to keep the evil Tempest Winds trapped on their island prison, keeps him isolated and alone. After seeing his father murdered by the Winds, he’s made an oath to keep them locked away. Besides, he prefers his work with his horses to annoying people anyway. But his powerful foes are rising, and when one infuriating, tempting woman arrives on his island, she threatens everything…

Bright, vivacious horse trainer Riley Donovan is drawn to big, brooding loner Lorenzo, and she’s planning to chase down the stubborn man once and for all. She knows he has demons, and it makes her own powers stir–powers she vowed never to use again when her mother was killed. But as their scorching attraction explodes, they find themselves in the center of a dangerous tempest…and now the fates of both their world and their hearts hang in the balance.
