The Oathborne Series in Order

About the Oathborne series

Series Premise

Street urchin Kaela Reign receives a mysterious invitation to Stonegarden, a secretive institute where elite recruits train in espionage, ancient magic, and survival skills to become Oathborne agents sworn to protect the realms. Thrust into a labyrinth of alliances, rivalries, and perilous trials, Kaela gains extraordinary powers, forges unbreakable bonds with fellow recruits, and confronts her deepest fears—while navigating intense attraction to two contrasting suitors whose own secrets could unravel everything.

The series is best read in publication order, as Kaela's journey from Year One through subsequent years tracks her escalating powers, deepening relationships, evolving rivalries, and the progressive uncovering of larger threats tied to the realms' fate, building cumulative emotional stakes and narrative momentum. That said, each book focuses on a distinct "year" of training and challenges with its own self-contained arc, major conflicts, romantic developments, and resolution, allowing readers to enjoy individual installments without prior context—though sequential reading maximizes the layered character growth and overarching destiny.

Main Characters

Kaela Reign — The fierce, resourceful protagonist: a clever street orphan who rises from nothing to become a formidable Oathborne recruit. Quick-witted, resilient, and fiercely independent, she grapples with newfound powers, self-doubt, and the weight of destiny while forming deep bonds and romantic entanglements.

- Erik Emberflame — One of Kaela's primary love interests: charismatic, fiery, and bold, embodying passion and intensity that draw her in despite the risks.

- Valerin Frost — The contrasting romantic rival: aloof, enigmatic, and coolly powerful, whose mysterious allure challenges Kaela in different ways.

Setting

The primary setting is the enigmatic, sprawling institute of Stonegarden—a labyrinthine fortress hidden from the outside world, filled with ancient halls, training arenas, forbidden libraries, and magical chambers where recruits hone espionage and arcane arts. The broader world encompasses four elemental realms (fiery, icy, earthy, and ethereal) sealed by ancient oaths, each teeming with unique magic, creatures, and cultures that Kaela and her peers must navigate during missions and trials, creating a vibrant, dangerous backdrop of wonder and peril.

Tone & Themes

The tone is thrilling, romantic, and immersive—fast-paced with high-stakes action, steamy tension, witty banter, and moments of vulnerability that balance danger with heartfelt connection. Rice crafts an exhilarating yet accessible fantasy that keeps readers hooked with unpredictability and emotional intensity.

Themes explore destiny versus choice, the power of found family and loyalty amid betrayal, self-discovery through adversity, the intoxicating pull of forbidden love, resilience in mastering one's gifts, and the clash between personal desires and greater responsibilities. Identity, ambition, sacrifice, and the transformative force of love and magic recur as driving forces.

In the end, Morgan Rice's Oathborne series is a captivating romantasy triumph—pulse-pounding adventures that weave espionage, elemental magic, and sizzling romance into an addictive saga of growth and destiny.
