This was okay. The setting didn't really interest me all that much, but I suppose it would be a big draw for a history buff.
The premise is rather interesting in that if these magical woods did exist, then they may have been a major contributor to conflict between Native Americans and settlers. It's natural to fear the unknown, and in this case that fear itself is the end of you. Sort of like a physical manifestation of "There is nothing to fear but fear itself". And interesting that prejudice kills in this case, because those who are most prejudiced, thinking of the other race as savages, are the ones most likely to die as though by savages.
The story just didn't strike me very strongly, and it quickly faded from memory. I don't even remember how it ends.
