The Silo Series was originally published in nine parts. The first book, WOOL, was released in July, 2011 as a short story. Four more parts followed, and these five stories were collected into a single novel, which went on to enjoy great success. WOOL told the story of Juliette, a mechanic in an underground silo who is given the job of sheriff. Juliette uncovers the mystery behind the underground world in which she lives. Following WOOL was the SHIFT series, told in three parts. Starting off as a prequel, SHIFT soon catches up to the events told in WOOL from a different perspective. The end of SHIFT and WOOL intersect, setting up the final chapter, DUST.
