Clash (The Arinthian Line #4)

Warlocks Augum, Bridget and Leera are finally able to relax after a grueling ordeal in Bahbell. Now their fugitive mentor has a dangerous new quest—sneak into an ancient library and research an artifact that could devastate the Legion.

Their substitute mentor Leopold Harvus, however, is an obsessive and petty man with a distaste for anything untoward, particularly Augum and Leera’s affections for each other. As their studies suffer from his meddling, one brazen act of rebellion plunges the trio and their quest into mortal peril, for Harvus quickly proves he is not a man to be trifled with.
