Brad Thor published three short pieces connected to the Scot Harvath series. Free Fall: A Prelude to Hidden Order (2013) sets up the events of the thirteenth Harvath novel. Epilogue II (2013) is a bonus chapter that extends Hidden Order’s ending. The Athens Solution (2015) is a standalone short story featuring Harvath.
These shorter works are extras for dedicated series readers rather than required reading. They were published as e-book exclusives and fill in details that the main novels gloss over.
