The book is up on Amazon ==> Niko and the Shades
Fifteen-year-old Niko can see the scarpies – sinister little shadow creatures who live in darkness and feed on black magic. Not just one or two, here or there, like everyone else. No, Niko sees them everywhere, scuttling along the streets, hiding in the shadows. And when a powerful figure at the royal court is murdered by black sorcery, Niko begins the think the scarpies are involved, which means he may be the only person who can stop a magical assassin before anyone else is killed, and a murderer takes control of the kingdom.
