Auctioned Omega — Kellan Larkin

Briar can only watch in terror as the wolves who attacked his pack fight in the omega auction for the right to own him. When the dust settles, the largest, most savage fighter steps forward, and Briar realizes with horror that he's been won by a rogue alpha. But Rohan isn't the monster Briar first takes him for.
In fact, Rohan is unlike any alpha Briar has ever met.
Rohan slowly begins to earn the frightened omega's trust through patience and tenderness. But with secrets and danger surrounding them, their bond will be tested repeatedly as they run from the violent packs trying to reclaim Briar. The two lovers are pushed to their breaking point, fleeing for their lives, and Briar discovers one more challenge for their perilous journey -- he's pregnant.
