Death to Magic — P. Katherine Barkley

Lex and Alex Knight are young twins who've been sent to the best magic school in the lands in order to be trained as hunters. According to a local prophecy, the Knight twins are destined to save the world's magic. You see, magic is dying out. It's being sucked away and destroyed by the creatures in the dark woods around the school, the vampires. But the twins aren't so sure that they're the ones spoken of by the prophecy. They struggle to hone their magic skills and find their place in the world of hunters. And just as they're settling in, the war with the vampires becomes a personal matter when the creatures attack and set fire to their hometown. It's a bleak start to their education, but things aren't always what they seem. There are more powerful spells and techniques that aren't usually taught to younger students. The school itself has a dark history that is never spoken of. And there's evidence that even the enemy vampires aren't all as evil as they seem. The world is full of secrets, and the Knight twins are seeking them out.
