Stealing Magic

After years of dedicated practice and service, Angela Thomas is finally a highly-skilled, newly confirmed Master of the Thieves' Guild, willingly accepting her duties as heir to Kevin Bennett, Merryweather's Guildmaster. Unfortunately, it seems that when a thief becomes truly adept, that thief gains some unsuspected abilities, and the Mages' Guild just might have something to say about that.
Someone steals spellbooks from the Vrolt mages, and Angela becomes the prime suspect. Who is leading the hunt and targeting her allies first? Is it an attack on her town, her guild, or her? Can she unravel the mystery and find the real culprit before everyone she knows is dead?
