Spirit Blade (en Inglés) - Glynn Stewart

Aaron Conner lives a quiet life. He waits tables at a local restaurant, helps keep the apartment building he lives in maintained, and is slowly beginning to realize the cute lawyer upstairs might see more in him than his handyman skills.

But he once walked a very different path. Strangeness at his new job wakes those old instincts, and the extraordinary breaches his carefully ordinary life once more.

He never meant to take up the blade again. He thought he never could. But when innocents are in danger, can he truly walk away?
