Who is L.S. Randolph?
The short answer is, he's Randolph Lalonde, an independent author who lives in Ontario. Canada. He's also the best selling science fiction author on the Amazon.com owned Mobipocket.com EBook website (for seven months and counting). That sounds impressive, sure, but in truth he's still a new author and Mobipocket isn't a very big site.
Randolph Lalonde writes full time, focusing much of his efforts on the Spinward Fringe space opera series of books. For more information and a quick bio you can check out the Wikipedia page.
Why take a pseudonym if you're only going to go public with it?
Many authors take a pseudonym for many reasons. In this case the name Randolph Lalonde is starting to become known for Science Fiction that's suitable for young adults up to adult readers. It's all rated PG-14 and thankfully many readers enjoy it a great deal. It's also important to mention that publishers and agents find it awkward when one author's name is attached to more than one genre. There are a lot of reasons behind that and I won't bore you with them.
A pseudonym can afford some creative freedom and that's the most important reason behind it in this case. I'd rather write horror unfettered by expectations set in my other work. Let's face it, horror is nothing without the terrible things that the genre tends to visit upon the characters trapped in the genre.
What kind of horror does L.S. Randolph write?
The first project is Dark Arts Rising. It's a supernatural / horror tale that begins with a series of terrible events. There's bloodshed in the first dozen or so words and the whole tale begins with a victim. Not typically what you'd see in the science fiction from Randolph Lalonde.
The second project may be RAGE³ (Rage Cubed), which follows the story of a serial killer from a unique perspective. It's looking like this novel will take a very, very long time to write and is well divorced from the Dark Arts Rising project. No hocus, no pocus, no supernatural aspects at all, just good old torture, murder, human evil and the chase involved in finding a way to stop it. Again, not exactly the kind of story you'd expect under the name of Randolph Lalonde.
Will there be other horror/supernatural projects? I have no idea. With enough support Dark Arts could be an ongoing series and considering someone's already donated a small but respectable amount in good faith that could be likely. I'm still writing Spinward Fringe full time, but there's nothing saying that another book or short story idea won't come along and you'll find yet another title attached to the name; L.S. Randolph (which is really Randolph S Lalonde lightly scrambled).
