League of Free Cadorie by Romana Drew

In an all-out war, the Cadorie don’t stand a chance against the invading aliens. They don’t even have aircraft. But there are other ways to fight. The League of Free Cadorie pits a gentle agrarian people against aliens bent on striping their natural resources. Overconfident and selfish, the aliens think they’re safe from the furry locals. They’re wrong.

Groomed from birth to be a famous singer, Kefan’s true genius lies elsewhere. Raised as a farm boy, Lannes never expected to discover invaders from space or be the catalyst for a revolution. Lenea joins her boyfriend, Kefan, and brother, Lannes, to stop the aliens from destroying her world, and becomes a hero in her own right.
