Wool: Omnibus by Hugh Howey was first published as five novella length e-books written while he was working at a bookstore in North Carolina. The story begins with a sadness that ripples through every word. Set far into the future, humans live underground in a huge silo. There is a rigid structure to the hierarchy of society within, supposedly for their own good, to prolong survival. But it leads to dissent as some are curious about what they glimpse through pixelated screens showing what's outside, and they will risk anything to explore.
Full of action and suspense, the characters are well developed and the story grips you from start to finish.
