Embers of Desire by Rowan Porter

A Heroic Imposter
All Falton ever wanted was to be captain of the guard. For years he trained to become a perfect machine of combat; a body rippling with muscle, and a mind focused on his goals.
Unfortunately, his dreams of leadership shatter with the arrival of R’yoma, a beautiful wanderer who arrives with a warning: an army of skull-faced monstrosities is marching to destroy his home.
As neighboring kingdoms fall to the enemy, Falton is forced to put his jealousy towards the newcomer aside and join an impossible quest to save his home.
The Mysterious Wanderer
A warrior with unparalleled ability, R’yoma never imagined himself as any sort of savior. He had spent years on his own, serving no lord or master.
Yet, when asked to lead an army in the hopes of saving the remaining Northern Territories from an adversary with unheard-of savagery and tenacity, he reluctantly accepts knowing the resentment it brings from the Lord’s handsome son.
Warriors Saving The World And Each Other
Regardless of his jealousy, Falton finds himself falling fast for R’yoma despite the danger surrounding them. The closer they grow, the more R’yoma’s dark secrets come to light. His prowess in battle, the haunted look in his eyes, and his iron-clad discipline are no coincidence. To survive the oncoming army, Falton must face R’yoma’s inner beast and put his trust to the ultimate test.
If they succeed, Falton may never see R’yoma the same way again. And if they don’t… death will come for them all.
