I'm not sure if this should go here or the general writing thread, but here we go. One of the many tips I have heard for new aspiring writers who want to get published is to write a novel without a sequel. However, in the era post Twilight (and some time before that, if I'm not mistaken) most of the commercially successful novels have been series of 3 or more books. And not by veteran authors, by first-timers! I know 50SoG started as a fanfic and grew a following before being published, so I can see how it was able to get published and become successful, but what about the rest? How do these people get signed? And if a new author is planning on writing and puplishing in the YA genre, shouldn't s/he plan for a series, instead of a single novel?
