Annexation — Marisa Chenery

Kiri has had the same dream for four years since she was twelve. She travels to another planet, where she meets a boy who teaches her to fight. Always bruised come morning, she knows it's no ordinary dream. After two years of no longer dreaming of Cax, she questions if she hadn't made him up. Then spaceships appear all over the world, and the boy she once knew is among the alien invaders. Orphaned and alone, Kiri uses the skills Cax had given her against his own people, wishing to hurt them as they'd hurt her. The flames of rebellion are fanned ever higher, and Kiri has a role to play that could cost her everything.
