Grak: Gnomercy — Joseph J. Bailey

After saving the spaceways by choking a ship-devouring demon with his fists before going on vacation to watch the Macroversal Wizarding Championships, Grak returns home to find the city of Alyon in turmoil.
 Or at least mildly disturbed.
 Citizens are disappearing.
 And the ones vanishing just so happen to be Grak's friends.
 Hounded by dimension-hopping ningnome assassins, Grak must track down his friends before they disappear permanently.

 Grak â€" Gnomercy is a quirky supernatural detective fantasy novel of roughly 50,000 words.
