This Omnibus Edition collects the five Wool books into a single volume. It is for those who arrived late to the party and who wish to save a dollar or two while picking up the same stories in a single package. The first Wool story was released as a standalone short in July of 2011. Due to reviewer demand, the rest of the story was released over the next six months.

And the ability to forget it ever happened. “These books by Hugh Howey absolutely define page-turner! ‘First Shift’ is part 6 in the Silo Series, a prequel to Wool 1-5.”
