Brianna R. MacMahon | A Multi-Award-Winning Indie Author | Page 3 of 3

A Little Bit About Me

My name is Brianna Riley MacMahon. I hold a master's degree in political science, which I attained from Syracuse University. (Go Orange!) I have been writing since I was a kid, but during the pandemic, I decided to try my hand at writing as a legitimate career. Do I still feel like a fraud from time to time? Of course. I don't think that ever goes away. But day by day, I'm gaining confidence!

When I'm not writing, I love to hang out with my family, read, go for long walks, play RPGs (big Star Wars, Fallout, and Elder Scrolls fan), and watch my favorite comfort shows on repeat.

Check out my most active socials below, and give me a follow if you so choose! (No pressure! But really, you'd be missing out! I tend to post lots of really cool stuff, so...)

This is where the fun begins!

Fast Facts

Let's talk about me! My favorite season is autumn, my favorite drink is unsweetened iced tea, my favorite dessert is a chocolate chip cookie skillet with vanilla ice cream, my favorite color is blue, and my favorite smell is a bonfire. Oh, and I love a good sweater.

I'm a proud INFJ, and my hobbies include staying at home, napping, and avoiding social interactions! I'm very comfortable in my own space, and I don't like being overly stimulated.

Now, I told you I'm a big Star Wars, Fallout, and Elder Scrolls fan, so I feel I have to go into my favorite characters from those three franchises. My favorite Star Wars character is R2-D2, my favorite Fallout character is Nick Valentine, and my favorite Elder Scrolls character is Brynjolf. My favorite Star Wars TV show? Andor. Do I love Fallout (the TV show)? Yes! And am I waiting for an Elder Scrolls one? Also yes! (But I'd rather have Elder Scrolls 6!)

What else? Well, I've been writing since I was a little kid, and I can hardly believe that I'm now in the position where I can share my stories and characters with the entire world! It's an absolute dream come true. Never stop believing in yourself, and never stop striving toward your goals!

"Every portrait that is painted with feeling is a portrait of the artist, not of the sitter." -Oscar Wilde, The Picture of Dorian Gray

"Maybe what really happened is this: the old fable-makers searched hard for a word to convey that what is gone is gone forever and never found it. And so, in the best traditions of where we come from, they gave their sorrow a name and drowned it." -Eavan Boland, "Atlantis: A Lost Sonnet"
