Nico Bravo and the trial of Vulcan

"Got a problem? The seasoned staff at Vulcan's Celestial Supply Shop--a kid named Nico Bravo, a sphinx named Lula, and a unicorn named Buck--have got just the thing in their inventory of magical merchandise. Vulcan is on trial, accused by the evil Ahriman of breaking the Cosmic Rule--interfering in the plans of a fellow god! His only hope is finding five powerful artifacts scattered across the globe. But is there more to this quest than meets the eye?"--Provided by publisher.
