Now that I've grabbed your attention, I'm sorry to inform you this post is about the novel Master Wolf by (shudder) Rose Estes. For anyone not familiar with Rose Estes, well she is notable for writing many of the popular Endless Quest books for TSR back in the day. This of course led to her being put on fiction for the Greyhawk setting (following on the heels of Gygax's Gord series) for which she is now and forever reviled by all corners of the community. Why is her Greyhawk novels hated? I won't go into that now, but you're better off not knowing.
Now I don't advocate book burning by any means even if it has Rose's name on it, so when I found a few of her Greyhawk novels in a library book sale years ago my goal wasn't to destroy them, but they sure have collected alot of dust. It's probably more because of the Greyhawk Adventures logo that I bought them since I'm a Greyhawk hoarder. Anyhow, on a random whim I finally opened one up with no intention of reading it, but instead to look at the art. Here, might be the silver lining to this book.
The cover above is by Clyde Caldwell whose richly colored paintings can be found throughout D&D on countless covers for modules such as the classic Ravenloft, and settings such as Dragonlance, Forgotten Realms, Mystara and more. His style is similar to contemporary Larry Elmore, but the way to spot a Caldwell painting is easy, just look for all the freakin' huge gems on his character's weapons and jewelry.
The interior art is an interesting find as well. Master Wolf contains a few black and white illustrations by a guy named Bart Sears. For those who don't read comics, he is a fairly famous comic artist primarily for his work on Justice League Europe. Surely Sears was still working his way up in the field when he got commissioned by TSR. This book came out in 1987, two years before his career boosting run on JLE. His bio mentions nothing about his work for TSR. I'd try and forget it too if it was for this novel.
You've stayed with me this long so I'm happy to tell you there is a rare Greyhawk map in this post and yes, it is in the novel Master Wolf. If you take this illustration of a tattered map out of the context of Estes' novel, it's actually quite good. This sketch of the Flanaess' northwest could be useful for any DM looking for a functional map to give their PCs on a wilderness jaunt. Just don't tell them where you got it... ;)
