Schooled in Magic

In another world, very different from ours and yet populated by people very much like us, a powerful necromancer casts a spell to bring him a Child of Destiny, with the intention of sacrificing the child for power. To his surprise, his spells brings him Emily, a lonely young girl from our world with a deep knowledge of history, a talent for magic, and a willingness to apply concepts from her old world to her new home. He prepares to sacrifice her anyway, only to watch helplessly as she is rescued at the last minute by another sorcerer and taken away.

For Emily, the shock of being kidnapped and nearly murdered is rapidly replaced by the awareness of being trapped in a world of magic; a world of powerful sorcerers and monarchs, and a magic school that can teach her the art but also a world of downtrodden magic-less commoners, unable to better themselves. As she comes to terms with her new life, and starts introducing concepts and innovations from her world, she starts to build a name for herself ...

... And discovers, too late, that the sorcerer who snatched her from her world is still after her.
