Mathis McGregor and her twin brother, Matthew, were tight. They were the best of friends and they were known simply as "The Twins" by everyone who knew them. They were the best wizards at Kensington School of Magic and the Divine. That was until Matthew was brutally murdered right in front of his sister. Now Mathis, a fire and precious solids user, must learn to go on and control the abilities that have been passed to her since Matthew's death. The problem? Matthew was an ice and regular solids user. When Elliot Aspendale arrives at Kensington, everything that Mathis learned from Matthew goes out of the window when a dark secret follows Elliot to Kensington. One that involves Mathis and Matthew, and one that involves the fate of the world of wizards.
