Structures of Earth – Book 1 of The Affinities of Magic
MAGIC WITHOUT UNDERSTANDING, AND A WIZARD'S GUILD WITH NO MEMBERS.
Young Rush has bent the rules and managed to become an apprentice in wizardry to his uncle, but neither of them is qualified to revive the Torch & Scroll guild, and there is no one else left. Neglected for generations, the mother house is in ruins, soon to be sold off by the Star Watch, the wizards' council, as the only guild to ever have expired for lack of heirs.
But this clever and deep-thinking young man may have puzzled out some of the fundamental principles underlying all magical practice, and this discovery will change everything, if only Rush can stay alive long enough for his plans to work.
