The Letter Mage

Aleph Worf-Sapir has spent all fourteen years of his life enduring the ravages of academic war, and he is over it. The second the Lunar University offers him a spot in an unprecedented peacekeeping effort-a student exchange program-he jumps at the opportunity. Aleph expects that he'll have a chance to bring peace to the University Moons, stop the bloodshed, and keep his home safe.
Yet nothing goes according to plan. The Prism Witches of the computing department lock him away. The Warlocks of the Gear are fighting amongst themselves. Soon after he leaves, one of Aleph's mothers is accused of murder back on the Glottal Moon. And to top it off, Aleph finds himself falling fast for a handsome spy from their origin planet-a place more dangerous than every department in the university put together. Aleph sees solutions to every source of conflict he encounters, but no one seems to pay attention to a kid.
Listen, Aleph didn't set out to be a supervillain. But he's quickly learning that no one's going to pay attention to him otherwise.
