Omega Captive of the Alpha Dragon by Wendy Rathbone

I’ve been sold to an unfriendly foreign land of dragon shifters to become a brood slave.

Tavi is a set-omega, which means he has no inner beast and cannot shift.
Considered worthless by his wolf pack, and with no individual rights, he is sold into slavery along with other set-omegas as they come of age.
Alluresh is a dragon shifter, all business and very little play. His inner dragon is feral and often controls him, shifting inappropriately at times, creating chaos and damage. Others fear him, causing Alluresh to become bitter and reclusive.
All of that changes when a shady friend from his past invites him to an omega auction. Alluresh attends, only to discover his dragon has eyes for one of the omegas for sale, demanding he bid on him or else.
What is Alluresh to do but obey his beast and call out a ridiculously large sum?
Two outcast men learn they might have more in common than they think, and a feral dragon finds his inner heart.

Contemporary omegaverse, alpha/omega, dragon shifter, mpreg/eggpreg, omega heat, knotting, opposites attract, age gap, size difference. This is a sold-into-brood-slavery tale turned romance where everything is consensual with a terribly sweet HEA.
