The Alchemy of Chaos (Maradaine Series 2)

Veranix Calbert is The Thorn—the street vigilante-turned-legend—and a danger to Willem Fenmere, the drug kingpin of Dentonhill. Veranix is determined to stop Fenmere and the effitte drug trade, especially when he discovers that Fenmere is planning on using the Red Rabbits gang in his neighborhood. But Veranix is also a magic student at the University of Maradaine, and it's exam week. With his academic career riding on his performance, there's no time to go after Fenmere or the Red Rabbits. But when a series of pranks on campus grow deadly, it's clear that someone has a vendetta against the university, and Veranix may be the only one who can stop them...
