How much gore is too much in horror books?

[AlexanderZPain]

What do you guys think about gore in horror books? I write zombie books, but I try not to overdo it on the bloody details. To me, a few details suffice to get the point across.

It's hard to quantify, but what do you guys think? How much do you expect in the genre?

It very much depends on the person. I've been in numerous horror book clubs, and when we've had a gory book choice, the feelings are usually quite divisive amongst the group as to where each person prefers the line to be drawn.
For me personally, I prefer gore in the more 'obvious' slasher-style novels. If I'm deep into a dystopian world or something complex and psychological, then I prefer the gore to be stand-out 'woah' scenes, rather than continuously graphic.
