Recruiting Libra by Eve Langlais

He’s shooting for the stars.
A professional hockey player on the verge of retirement, Grayson is playing his final game when disaster strikes. When monsters explode from the ice, he risks his life to save as many as he can and is fatally injured in the process.

Only, instead of dying, he is reborn.
He’s been selected by the stars to become a Zodiac Warrior—whether he likes it or not. So much for drinking beers in his hot tub and reminiscing about his glory days on the ice. He’s now expected to fight evil, starting with the alien creatures intent on decimating humanity.

It’s the most important game of his life and, if he succeeds, he’ll end up with something better than a dusty trophy on his mantel.
He’ll win at love.
