The Vet’s Christmas Familiar by TJ Nichols

Wounded and left for dead, shifter Kit Linfield is stuck in his eagle form.

A Christmas Eve flight with his family turned to slaughter when some hunters took aim. Kit played dead, but he needs help, or he’ll die. He wants to live to have vengeance.
Errol Hart is spending Christmas alone for the first time since his divorce. When a badly wounded eagle is delivered to his care, it’s the first animal that Errol can’t communicate with. The eagle is so badly injured Errol isn’t sure it will survive. But the way it looks at him, like it understands every word he says…
When Errol learns the truth, he vows to help Kit find the men responsible for the illegal hunt.
