The Academy of the Fae

At a secret high school for human and fae students, the top subject is the fate of Earth.
An advance ship of space fae volunteered their teens for an exchange program. Humans and fae must learn the others' languages and cultures to make a treaty when the rest of the fleet arrive from their old planet. A little friendship wouldn't hurt matters, either.
But not everyone is willing to play nice at recess.
Though some are taking advantage of the new lessons, others prefer their old ways. Bullies, prejudices, and private agendas threaten the tentative peace. The fae must be kept secret until graduation, but the teens face tests on every side.
Flunking is not an option. Too bad cheaters might ruin everything.
Contemporary YA fantasy with a dash of sci fi & mythology, from the author of Unexpected Heroes.
