A school for sorcery

"In this school, the final exam could be a real killer. Both apprehensive and excited about her new school--The Lesley Simonton School for the Magically Gifted--Tria Tesserel is nevertheless unprepared for her biggest shock of all: her roommate, Lina. Impatient with rules and homework, Lina violates Simonton rules by using her power at will and against whomever displeases her. Unlucky for Tria, that includes her. Meanwhile, evil magic is brewing at the school, and it will be up to Tria to face it ... if she can handle her roommate, that is."
