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.
"Feel that, Levi? Feel it all. This is what it's supposed to be. This is what's real."
My pathetic, hopeless romantic heart loves those lines. My favorite in the entire book.
