Stop! If you haven’t done so already, read The Quest to Save Landon and When Hell Boils Over first.
After giving Alfred and Merlyn Landon’s invisibility cloak, and making sure they entered the secret entrance to the Moose King’s castle, Buddy the Ambrosial Dragon used a separate and most secret entrance himself, this time straight to Hell, or as close as he could get without being dead or dying. Asmodius, the head of all of Hell’s demons, wouldn’t expect him to enter their realm by posing as one of the dead on a barge crossing the River Styx.
The dragon, Landon, and their magical companion Yao Jin had been exceedingly lucky to escape this place in the past. But he couldn’t let Landon die, and he would do anything to save the boy, including sacrifice his own life and soul. However, there was more involved in his quest than even that.
