Warlord's Prize (Midlands Omegas Book 1) by F.A. Lantern

Prize. Bribe. Distraction. Omega.Whatever they call him, Brook is doomed. Sold to a brutal Warlord to keep him from his homeland’s gates, Brook is hardly worth the reprieve. As a male Omega, Brook is unlikely to be Mated, so the brightest future he can hope for is that of a neglected concubine. He is willing to risk a far worse future than that one to give his siblings a chance to escape their father’s weakening grip, but when Sebastien is far different from Brook’s imaginings, is he willing to sacrifice his family and his freedom to be The Warlord’s Prize?
