The code for indent is already there, but text-indent is set twice in the css-file for that class.
If you use sigil, or tweak epub in calibre, it's easy to fix the missing indent. Just remove text-indent:0.0px;
It's a great series, though I like the first three more than the rest. They can be a bit graphic, a scene in the first book I read (no 2) made me nauseous while reading it.
I don't normally get nauseous like that, and the cannibal-book (Flesh House) didn't bother me at all
