There usually has to be some sort of romance involved for me to pick up a book. Anything with a strong emotional undercurrent is bound to get my attention. Contemporary, PNR, H/C & M/M are my favorites.
This is probably the sappiest, most romantic bdsm series I've ever read. That's not to say it's badly written, because it's not, by far... it's just different. It's not what I expected, but I find myself enjoying it nonetheless. I like Tobias and Noah.
