books accordingly. If buyers want one genre over another, the marketer wants to save them time, by letting them know more about the main characters or what the story may be about up front. In today's get it fast world, a decision to buy a book is not pondered, it happens quickly. Mulling over a purchase is quickly becoming passe. Marketers subscribe to the buying publics buying habits.
PS: In case you're interested (and for full disclosure), I listed the following as categories I'd feel uncomfortable or unqualified to critique: traditional fantasy, high fantasy, no elves or were-seals (the latter I actually meant as a joke, because I bet there's a good book out there with an insanely well-written romance with elves or were-seals). So, maybe I need to check myself, huh?
