Dark Stranger by Kate Douglas

Berserkers. Chanku, but not. Born as animals, but unlike their more civilized brethren, they have no access to the Tibetan grasses that give Chanku their shapeshifting abilities. They are refugees of the same alien world, aware of their humanity yet living and dying as animals on earth.

Untold numbers of shapeshifters in zoos…in the wild…in cages as victims of predator trafficking rings operating worldwide. Unable to know their true selves, unable to fully mate with the ones they love.

The pack knows they exist. Knows that they are the only ones with the power to save their feral brethren, but the clock is ticking. Chanku are almost immortal, but Berserkers live and die on their animal’s timetable…how many will the pack rescue before it’s too late? Will they ever save enough of their brethren—different yet so much alike under their skin?

The hunt is on.
