As a reader this concerns me.
I can only stand so much angst in a book. Sorry all you angsty writers out there! Yes, I want a happy ending! I am a romantic as well as a romance author after all. I just like a lot of verity. Maybe I bore easily. I adore the sub-genres, be they erotic, paranormal, suspense, or what have you. I want some twists and turns to the "hero meets heroine + angst and more angst+hero saves the day= HEA. Maybe I watched too much Scooby Do as a kid, but toss in some mystery, some social commentary a monster or two and I'm a happy camper.
What floats your boat?
