Unnatural magic
(Book)

"An enchanting debut historical fantasy starring a young woman with an incredible natural talent for sorcery. Onna Gebowa is determined to become a great wizard. She can write the parameters of a spell faster than any of the young men in her village school. But despite her incredible abilities, she's denied a place at the nation's premier arcane academy. Undaunted, she sails to the bustling city-state of Hexos, hoping to find a place at a university where they don't think there's anything untoward about providing a woman with a magical education... Tsira is a troll who never quite fit into her clan, despite being the leader's daughter. She decides to strike out on her own and look for work in a human city, but on her way she stumbles upon a body of a half-dead human soldier in the snow. As she slowly nurses him back to health, an unlikely bond forms between them, one that is soon tested when an unknown mage makes an attempt on Tsira's life. Far away in Hexos, the newly arrived Onna is also drawn into a mysterious, magical attack on a troll. Trolls have lived alongside--and been revered by--humans for generations, but now it appears they're being targeted by a sinister sorcery. And Onna and Tsira both begin to devote their considerable abilities into figuring out how to stop the deaths before their homeland is torn apart.." --,Provided by publisher.
