The listing, 4 1980's Dungeons & Dragons Choose Your Own Adventure Books! has ended.
This auction is for 3 1980's Dungeons & Dragons Endless Quest Books!: Found another one that I'm adding!
#8 Villains of Volturnus - 1983
#12 Light on QuestsMountain - 1983
#21 Duel of the Masters - 1984
#33 Knight of Illusion - 1986
All books have a diagonal line made with a black magic marker in the upper right-hand corner of the cover and book #33 has some very minimal damage at the bottom of the corner that you can barely see. Other than that, books are in great condition! They are written in the same vein as the Choose You Own Adventure books!
Thanks for looking and have a great day :)
