Emily Jane Buehler
Author

Emily Jane Buehler writes cozy fantasy romances where everyday people (and fairies) have adventures and fall in love. Her stories are lighthearted with action and adventure, love and magic, and protagonists who learn to believe in themselves and find their courage. And yes, they are kissing books. She thinks of them as the beach reads that Princess Eilonwy packs when she goes on vacation. Emily Jane believes that by portraying positive relationships with good communication, romance novels can help readers envision such connections for themselves, model consent, and portray diverse types of relationships and people. They can be a fun escape while still having depth and contributing to a better society. Emily Jane has a chemistry background and worked for years as a bread baker before publishing her first book, Bread Science: The Chemistry and Craft of Making Bread, which includes the science of bread-making as well as the step-by-step process. She teaches baking classes at the Campbell Folk School in western Carolina along with her sourdough starter, Rocky Baldougha. She has also published a memoir about her bicycle trip from New Jersey to Oregon called Somewhere and Nowhere: A Bicycle Journey Across America. Emily Jane lives and works in Hillsborough with a bossy, bite-y cat named Coco. She is a freelance copyeditor of science papers. When she has any free time, and even when she doesn’t, she likes to hike with her partner, write paper letters to friends outside of Kim’s Bakery, and defuse Coco by letting him kill his feather toy. She is online at https://janebuehler.com and https://emilybuehler.com.

Kelly Grayson

H.P. Holo
Author

H.P. Holo grew up in a family where it was dangerous to say, “I’m bored.” She’s also an incorrigible smart aleck. So when her parents told her to fix her boredom by reading a dictionary, she did. And then, just to be extra sassy, she began writing novels that required them to keep that dictionary handy. Her first ode to smart aleckery was The Wizard’s Way (with Jacob Holo), a tale of awkward steampunk wizards and dapper swordfighting pugs, and as much a love letter to steampunk as sassery. She followed it with another sassy love letter in the redonkulous Monster Punk Horizon series, this time to all things monster hunting, collecting, and befriending. Her most significant ode to smart aleckery, though, is the entirety of her second, spicy pen name, Edie Skye. H.P./Edie wrote the mecha harem fantasy Titan Mage as a joke, expecting only her husband and a few Gunpla nerds to read it—so naturally it became an Amazon bestseller. In the process of writing the Titan Mage series, though, she also discovered that while she likes writing smart stuff, she also likes writing smut stuff. Pretty spicy smut stuff, too, ’cause if you’re gonna do it, you might as well do it hard. If all her books are also love letters, then this series is a love letter to sexy people in giant robots and the chili emojis they get up to. On both her pen names, she likes to spin fun (and funny) fantasies about rollicking adventures, absurd monsters, the bonds of friendship, and general nonsense. When not writing, she enjoys procrastinating, fangirling over terrible movies, arguing that Cloudy with a Chance of Meatballs is, in fact, the most perfect movie ever made, and having Too Many Fountain Pens. She lives in South Carolina with her husband, the judgmental ghost of her former cat/boss, and a new kitten whose hobbies include furniture parkour at 3AM, climbing up door frames, screaming for no apparent reason, chewing on books, and trying to lick the occasional light bulb. (Yes, he is orange.)

Jacob Holo
Author

Jacob Holo has been a recreational geek since childhood, when he discovered Star Wars and Star Trek, and a professional geek since college, when he graduated from Youngstown State University with a degree in Electrical and Controls Engineering. He started writing when his parents bought that “new” IBM 286 desktop, and over the years, those powers combined to push him to the next level of nerddom: a sci-fi author who designs intricate worlds and tech systems…and promptly blows them up in a string of nonstop action. He is the author of over fifteen books, including the bestselling Gordian Division series (with David Weber), YA urban fantasy Time Reavers (a Kirkus Reviews Best Indie Book), and fantasy adventure Monster Punk Horizon: Excess (with H.P. Holo). Between novels, Jacob enjoys gaming of all sorts, whether video gaming, card gaming, miniature wargaming, or watching speed runs on YouTube. He is a former-Ohioan, former-Michigander who now lives in South Carolina with his wife/boss H.P., the ghost of his cat/boss Nova, and his new kitten/boss Dazzle, who is a very good boy even if he does try to lick light bulbs.

Author

Wife and a mother of five, J.F. Posthumus is an IT Tech with over a decade of experience.

An avid gamer, she loves playing Dungeons & Dragons, and a variety of other board games with her family and friends. She’s also a hopeless romantic, thanks to all the fairy tales she cut her eyeteeth on. They were what J.F. Posthumus learned to read before she discovered the Boxcar Children Mysteries. From there, she fell into the rabbit hole that’s reading, where she discovered a love for mysteries, fantasy, and the occasional romance. Since writing was a favorite subject, she naturally incorporated her love of murder, mysteries, and fantasy into her works.

Scott Sykes
Author

S.M. Sykes never saw himself as a writer, facing struggles with English classes in school. Even his wife, who doubles as his editor, can attest to occasional challenges with organizing his thoughts. However, despite these obstacles, he discovered a passion for storytelling that he couldn’t ignore. Beginning with his debut novel, Eyes of Blue in 2018 at the age of 38, he found the genesis of his stories in a simple idea that sparked in his mind. As the narrative unfolded, it took on a life of its own, leading to the ongoing series that began with Eyes of Blue and continues with his current project, Loss of Blue. With Loss of Blue, he aims to weave together the threads of his previous works into a conclusion that is both profound and satisfying. Balancing a full-time job with his writing endeavors, which include advertising and marketing his work, has proven challenging. Yet, his motivation lies not in financial gain or replacing his day job but in the satisfaction of sharing his ideas with readers. Looking ahead, he remains focused on his writing journey, eager to explore where it may lead. He invites others to join him on this adventure by checking out his books and sharing their thoughts.
