Bringers Of Magic — E. Rose Sabin

Wonder workers have come to the town of Carey in Arucadi's heartland, and the town will never be the same.
Ed Robbins, known to the townsfolk as Simple Eddie, discovers that he is magically gifted, and his life is transformed. Abigail Dormer, respected headmistress of the Dormer Primary School for Young Ladies, does not believe in magic and is convinced that Kyla and Marta are charlatans until Abigail's own magic abilities reveal themselves, much to her consternation. Jerome Esterville, rebellious son of a pious mother, also discovers a gift, but it is wild magic, not from the Power-Giver, and if not restrained will turn him to terrible evil. Councilor Hardwick, head of the Carey City Council, hopes to receive power and, when that gift is denied him, sets the council and most of the town against the "wonder workers." Devastation looms for the town, and Kyla and Marta face death. Ed's magical gifts may provide a solution, but only if Kyla and Marta can train him before disaster overtakes them all.
