Rio Grande Fall — Rudolfo A. Anaya

Everyone loves the Hot Air Balloon Fiesta de Albuquerque. This year the fiesta is more profitable and livelier than ever. Until a body plummets from the heavens. PI. Sonny
Baca immediately recognizes the corpse as a key witness in his cousin's murder case. When another balloonist is shot down and the fiesta offers him a handsome reward to catch the killer, Sonny is soon following a sinister trail leading to a world of black magic, corruption, and drugs. Here his enemy is not only of this world, but of its shadow, and here Sonny must risk his very soul for the fate of the city--and the woman--he loves.
