“The Gathering of Heroes” is the third book in the Dark Border Series. The first two books were:
“The Lost Prince” 
all of them have intense military drama, great battle scenes and fantasy elements from a unique world. I was sorry to hear Paul Edwin Zimmer had passed. The series had ongoing potential.
Back Cover:
Y’gora is threatened…
Goblins, demons and worse spill over the Dark Border, attacking Rath Tintallain and the priceless treasure it holds. The Hasturs fear that the fall of Rath Tintallain will bring utter destruction, and summon a gathering of the greatest heroes—elves, dwarves, and mortal men—for desperate stand. And Istvan DiVega is called to join the fray, fighting shoulder to shoulder with men of legend. They are the last defense against the Shadow…
If you can find copies of one, or all three, it is worth your time.
