"I do have a small collection of traditional SF ideas which I've never been able to sell. I'm known as a fantasy writer and neither my agent nor my editors want to risk my brand by jumping genre"

This quote by Lynn Abbey suggests that she has a collection of science fiction ideas that she has not had the ability to offer. It appears that she is referred to as a fantasy writer and her agent and editors are not ready to take the threat of her leaping genres. This might be due to the fact that they are fretted that her fans may not be interested in her science fiction work, or that she might not be as effective in the category. It might also be that they are stressed that her brand may be damaged if she does refrain from doing well in the category. Whatever the factor, it appears that Lynn Abbey is stuck in a tight spot, as she has a collection of sci-fi concepts that she is unable to sell.
