Mercury Hale is out of a job. That's not stopping him from fighting crime in San Camillo - for a fee, of course. His much simpler yet financially unstable situation is interrupted when Procyon Foundation comes to him with a problem: one of their top Tracking specialists is missing. The good news? Mercury may have found a way to get back into his employer's good graces. The bad news? A new breed of monster is terrorizing his city. Couple that challenge with the emergence of a rival force to Procyon that wants astral fiends for experimentation, and the appearance of a mysterious stranger who's traveled across dimensions, Mercury has his hands full juggling dangers - and grappling with a lovesick heart. And if he drops anything, he could lose it all.
