i think the cover (toms feet(?) aside) and description are fine if you (like me) are looking for something more original away from mainstream fantasy.
while the cover isnt especially well done it does get the main theme across (demons).
i read quite a bit and iam now at a point where i sometimes get sick to my stomach by some of the fantasy “literature” out there.
when i read the description for into the abyss i was pleasantly surprised because it seemed refreshingly different, almost custom-made for me.
so while the description may not convince your average fantasy reader, it probably will convince those who have had enough of tolkien, jordan, etc.
