Ronan

2025

It's been almost a century since the veil fell and monsters invaded the world. We didn't give the humans an opportunity to retaliate as we charged in and took over, and I was at the head of the front lines with my sword in hand. A perfect soldier, fighting the battles that ultimately put my people in charge of this planet. Half of humanity was slaughtered, and in the decades since the invasion, things have only gotten worse. Tensions between the rebel humans and monsters grew as the climate changed, and temperatures rose as resources dwindled. The sun scorched away plants and trees, leaving behind a husk of a planet where everyone fights for survival. The Fates were furious at our violence, and now we're trapped inside the hell we created. We've all heard tale of the Mate's Mark, and how we're destined to find our fated mate. One human, one monster - foretold to be the cure to this cursed world and repair the damage that has been done. What was once the cause of curiosity and intrigue has turned into nothing more than a mockery. Decades have passed, and not a single pair of fated mates had been found. Until now. Until me. Until the night I pull off my armor and find the mark staring back. Author's note: Ronan is a First Person Dual POV MM Monster Romance series with explicit content intended for readers 18+. It is the first in a series that will have an overarching storyline carrying between books. While this series ends with a guaranteed HEA, individual books end on more of a HFN basis. The feature couple's story will be resolved, though there will be some unanswered questions and mild cliffhangers that lead into the next in the series.

2025

For almost a century, we’ve believed the prophecy to be a hoax. The promise of Fated Mates being the cure to this ruined world was a beautiful story, a romantic lie told to keep us in line. Nothing more than an idyllic promise to make us work together. Only we never did, and the world only suffered more. Joining the military has turned my life into a monotonous cycle of schedule, routine, and order. Day after day, I wake at the same time, and wear the same uniform, and stare at the same power-hungry faces I’ve been commanded by for decades. Days blur into weeks, and weeks turn into years where it feels like nothing ever happens. Nothing ever changes. Until the day it does…. The prophecy is real, my best friend has disappeared with his mate, and now I’m here, alone, keeping my last promise to him. Protect August. It’s not hard to track him down, but the human is the last thing I expected. August, a medic, is confined to a cell with the rest of his rebel friends, but despite this waste of a world and the terrible things he’s seen in this life, he’s good. Sunshine and smiles, endless curiosity and infallible happiness. He views the world with a positivity I can’t figure out, and it pulls me into his gravity, eliciting conflicted feelings that have no place in a warrior like me. In a life that’s riddled with darkness, August is light, and I can’t seem to look away from his glow.

Ninety-one years ago, I stumbled upon a window to a strange new world. Beyond, there were blue skies and odd trees, and flowers like nothing I’d ever seen. Curiosity got the better of me, and life as I knew it changed forever. Ljómur was the military’s best kept secret. Behind those walls, I was experimented on and studied, torn apart and put back together. Caged, collared, and stripped of any sense of identity I once had. A lifelong prisoner. Now I’m free, and my former hell has been destroyed. Every bar that once confined me lies in ruin, yet I still can’t escape my cage. It’s been a month since we discovered what the military was trying to do, and since I swore to bring the group to the rifts. Ever since, I’ve been living in fear of the day they’ll call on me to fulfill that promise. No one knows better than me what’s at stake, but most days, my mind is not my own. When I’m lost inside my thoughts, only one person is able to reach me. Reyes breaks through the clouds and pulls me from that dark place in a way the others can’t. He tells me I still have something to give, but I’m not so sure that’s true. I’m just a broken thing, after all, and those can’t always be fixed.

2026

At Ljómur, surrounded by mates, we saw firsthand how fate could rewrite lives in an instant. We never thought it would claim us too. Everything was perfect. Bash was my peace, my home, and the one person who saw through every layer I hid behind. Until the day I shattered it all. Four years ago, I sent him away without explanation and forced him to believe our love had been a lie. Now our group needs Bash’s brilliant mind, and since the military believes I’m dead... I'm the perfect ghost to retrieve him. When I agree to find him, I brace for hatred, rejection, protest, and tears. But all my practiced detachment and unbothered smiles don't prepare me for facing him again. The Fates have dragged us back together, tearing open old wounds in a world on the brink of fallout. With the scars I bear and the secrets I keep, is it too late to reclaim what we lost? Or can a broken mate find his way back to the only heart that ever made him whole?

Author · 19 books

G. Eilsel started writing under this pen name in early 2024, publishing works in two genres she loves: eccentric novellas and MM romance. Her writing puts a focus on sarcasm, snarky humor, sometimes horrible puns, and steamy scenes that'll make your momma blush. Expect heavy spice, in any sort of variety you're looking for-sweet, emotional, depraved, or downright questionable. Some of her books are one-handed reads with minimal plot, others are more intricate stories that weave themselves through her brain and demand to be put on paper. Angsty and emotional, light and giggle-inducing, and everything in between can be found between the covers of her books. She doesn't take herself too seriously, throwing pieces of her humor and quirky personality in her writing. If she can't live up to her title of a One-Handed author, then maybe she can at least make you smile.
