Unseen Past by Kaje Harper

Twenty years before Simon found Paul, a decade before Aaron joined the Minneapolis West pack, there were other gay wolves living hidden lives.

Sawyer Holt thought he was dead at the age of sixteen when his brother Leon caught him kissing a human man. Dragged up in front of his Alpha, he could only hope for a painless end, especially when Rick Brown stared at him with an icy gaze and said to Leon, “I’ll take care of it.” Except what Rick gave Sawyer wasn’t death, but a new concealed life.
In Minot, North Dakota, Sawyer has spent fourteen years isolated among humans, carving out a future for himself. Until a messenger arrives from Rick, saying that Leon has discovered the ruse, and it’s time to run again. Sawyer’s furious about losing his hard-won life, but intrigued by the young man carrying the message.
James Ferguson doesn’t appreciate being sent from his home and pack in Virginia to run errands for the Chicago Alpha, but as Twelfth out of twelve adult wolves, he’s in no position to complain. He figures he’ll deliver the message and package, and hurry home for Thanksgiving. But a snowstorm, and the huge, muscular, confusing werewolf who rescues him, upend his plans. Soon, James’s whole world changes, and the only future he may have depends on whether he and Sawyer can survive being hunted, together.

Unseen Past is a prequel novel set in the world of the Hidden Wolves, twenty years before Book 1.
