Literary agents for speculative writers
It takes a lot of time to trawl literary agencies to find agents who are willing to represent speculative fiction writers, I've done of the work for you with a list here. Plus, where possible, any relevant authors who they represent. Remember when contacting them to adhere to their submission policies rigorously. If you receive a rejection, don't forget it may not be because your work isn't good enough, it may be decided by their List. Agents handle a combination of authors, people with commercial potential combined with commercial income. Agents make their salaries from what their authors earn. Therefore, they take on only a handful of debut writers because the income they generate is not guaranteed, they are a risk. Your work might be brilliant but if their list has a lot of debut writers, they won't want to take on any more because it would affect what they earn. They are entrepreneurs!
With that in mind, here are some agents you might want to approach:
Curtis Brown - not only a literary agency but Curtis Brown Creative is an agent-led writing school. Their courses are in London and online. Courses range from tutor-led write-your-novel to how to edit and pitch your finished work to an agent. Courses always include contact with their agents.
