Publisher's blurb: Fai Chen reveals that a draft of the Hellriders’ original attack plan might still exist, but it won’t be easy to get it. If you can recover these, it would be extremely helpful in your quest to locate their remains and free their spirits. It might very well be a suicide mission, but when you’re in Avernus, what isn’t? Fortunately, the wily merchant has just the plan for a group of heroes unconcerned with the odds. Part Two of the Behind Infernal Lines series.
