I picked this book (the edition seen here) in late 1986 or early 1987 from a Stars and Stripes bookstore in Japan. Doing some casual research on the book turned up a free to read copy at archive.org: https://archive.org/details/dicingwithdragon00ianl

I'm undecided about writing about this book. As I've mentioned elsewhere, I was mad for fantasy work, and the paperback was getting a bit of traction already for role-playing games.

But it does include a solo adventure, and I did a fair bit of those back in the day.
