Starfall

Three things as vast as the world itself fell from the sky, overturning everything. A youth awakens to find the world ruled by "gray" "gods"—gods enthroned on high, twisting all living things, drinking blood, feeding on humans. The youth eats gray crops, treads gray earth, walks out of the gray mountains, and looks up toward the direction from which they fell—there, a gray starry sky. — Description from novelcodex.orgFull novel: Starfall — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
