Rook (Bridge & Sword #1) by JC Andrijeski

Seers, the mysterious race of beings discovered on Earth, fascinated Allie since childhood, since the first time she went to see them in an exhibit with her father at the Oakland Coliseum in California. But you have to be rich to own a seer, and it’s illegal to let them roam uncollared, since they’re dangerous as hell. As a waitress and college dropout, she only sees them at a distance, until Revik bursts into her life, and Allie is thrown into a world behind the world, one most humans never dreamed existed. Psychic romance. Apocalyptic.
